Arnold Schwarzenegger was just involved in a bad car accident  ... so bad his monster SUV rolled over on top of another car, and that driver was badly injured.

Arnold was driving a Yukon SUV when it collided with a red Prius at around 5:00 PM PT.  His SUV started to roll and ended up on top of the Prius, then continued rolling to the left into a Porsche Taycan.

One eyewitness says it was crazy ... it looked like a stunt in a movie. The collision was intense enough that the airbags deployed on the Yukon.

The woman who was driving the Prius was injured -- bleeding heavily from her head. We're told an ambulance took her to the hospital.

Arnold, we're told, is OK and is deeply concerned about the injured woman. An Arnold source tells TMZ he wants to personally check up on her.

Jake Steinfeld of "Body By Jake" fame was apparently at the scene at the time of the crash and that's him in the photo (above) with Arnold. The two are close friends. In fact, when Arnold was Governor of California, Jake was the Chairman of the Governor's Council on Physical Fitness.

One of the witnesses says it appeared the Prius was on Sunset Blvd and Arnold was on Sunset turning left in the opposite direction when the collision occurred.

At the time of this post, Arnold is still at the accident scene, which is about a mile from his home.

Baker Mayfield finally had surgery on his injured shoulder Wednesday ... and he said it went so well, he's hoping this is a step toward getting back to his "true self."

The Cleveland Browns QB initially injured the shoulder in September while trying to make a tackle following an interception ... and he never seemed to be quite right afterward.

He struggled all year long ... throwing 13 INTs to just 17 TDs, and the Browns ended up missing the playoffs.

But, Baker said just hours after surgery wrapped that he's confident he can now get back to his pre-injury level -- even though the rehab road promises to be grueling.

"It's not going to be an easy one," Mayfield said, "but it's going to be one I'm going to remember, and it's going to be a special one."

Baker added, "This is not the end of my story."

Abby Lee Miller endured a painful nightmare when a hotel door fell over on her, crushing her for nearly a dozen minutes ... according to the lawsuit she just filed.

The "Dance Moms" maven says she was staying at the Hampton Inn & Suites in Santa Monica back in August 2020 when she wheeled herself into the bathroom of her room. Remember, Abby's been in a wheelchair since 2018 due to her lymphoma battle.

In docs obtained by TMZ, Abby says she was leaving the bathroom when her back left wheel got caught under the sliding bathroom door -- and when she attempted to free herself, the more than 300-pound door came crashing down. She says she was pinned in her wheelchair and trapped in the doorway for 6 to 12 minutes.

According to the suit, Abby screamed for help until 2 hotel staffers came to lift the door off of her. She was taken by ambulance to a nearby hospital, and Abby says she's still going through physical therapy for the injuries she suffered to her head and shoulder.

The alleged falling door would've been more than enough trauma, but in the docs, Abby says she endured other hardships during an extended stay from March to October 2020. For instance, she claims the laundry room was not accessible to wheelchairs, her hallway was often blocked by housekeeping carts ... and she was unable to open doors to the pool or gym areas, presumably due to her disability.

Abby is suing the hotel's parent corporation for negligence, emotional distress, discrimination and false imprisonment ... and she's seeking compensation of at least $8.5 million.

Cleveland Browns defensive lineman Malik McDowell was completely naked while he was being arrested on Monday ... new video, obtained by TMZ Sports, shows.

In the footage, you can see the 6-foot-6, 290-pound football player did not have a single article of clothing on his body ... as officers tried to subdue him in Deerfield Beach, FL.

McDowell, who had cuffs on his wrists and shackles around his ankles in the clip, appeared to be very agitated with cops, writhing on the ground nearly every time an officer got near him.

At one point, you can see in the video, a cop appeared to kick McDowell to keep him on the ground.

Eventually, McDowell was loaded onto a stretcher and taken away from the scene.

As we reported, cops say in police documents that McDowell stripped naked and was seen walking around near a school.

Officers say when they found him and confronted him, he attacked -- with one cop alleging the football player told him "f*** you" and then "charged at me ... at full speed with closed fist."

The officer claimed McDowell struck him so hard and so many times, he suffered injuries in the altercation -- including a badly swollen eye.

Cops say they were eventually able to take down McDowell using a taser. He was ultimately booked into jail on charges of aggravated battery on an officer, resisting and exposing sex organs in public.

The Browns released a statement on the arrest on Tuesday, saying, "We are aware of the very concerning incident and arrest involving Malik McDowell and are in the process of gathering more information."

"We understand the severity of this matter and our thoughts are for the well-being of all involved. … No further comment at this time."

Very scary moment during the Cardinals vs. Rams playoff game on Monday ... Arizona star Budda Baker needed to be taken to the hospital following a violent collision with an L.A. player.

In the third quarter of the Rams' blowout win, Baker -- a Pro Bowler this season -- was attempting to make a tackle on Cam Akers, when the two brutally slammed heads.

Video of the play shows Baker immediately went limp, appearing to be knocked unconscious as soon as the impact happened.

The 26-year-old laid on the ground for several minutes, before trainers strapped him to a backboard and eventually loaded him into an ambulance.

Thankfully, the Cardinals announced their star player never lost movement or feeling in his extremities ... and was both alert and communicative.

Baker later tweeted he's doing "good" ... writing, "Thank you all for the prayers. I am doing good."

There's been no word yet if the Arizona safety has been released from the hospital.

Akers -- who actually taunted Baker following the hit -- apologized for his actions ... saying in a tweet of his own, "I didn’t know he was hurt after the play but I have nothing but respect for him."

The Cardinals season is now over following the 34-11 loss, while the Rams will travel to Tampa Bay this weekend to play Tom Brady and the Buccaneers.

Get well soon, Budda.

A surgeon, who's also a Delta Sigma Theta sorority member, is apologizing for posting pics from a patient's procedure ... all to plug a historic day for her sorority.

Dr. Nicole E. Williams ruffled a lot of feathers by sharing photos and info about the surgery she performed on January 13 -- she boasted about removing 22 fibroids from a patient who's a member of another sorority ... Alpha Kappa Alpha. The photos showed the fibroids on a table next to Dr. Williams who was making the Delta hand signal to rep her sorority.

That day also happened to be founders day for Delta Sigma Theta, so the good doc thought she'd show some pride -- but it totally backfired as she faced swift online backlash.

Dr. Williams has now deleted the original post and backtracked, saying ... "A terrible decision was made. I unequivocally and prayerfully apologize for any hurt I may have caused."

A lot of the outrage came from folks who felt she was violating a patient's privacy simply to promote her sorority.

She did provide a history lesson in the original post, pointing out the 22 members who founded DST in 1913 had broken off from Alpha Kappa Alpha sorority.

Josh Allen might wanna avoid taking Bart Scott's advice and poppin' Viagra before Saturday's playoff game ... 'cause the makers of the blue pill are warning NFL players to talk to a doctor before using their product.

A rep for Viagra tells TMZ Sports the medicine should only be used for its intended purposes ... even if Scott swears it'll help with blood circulation in cold temps.

"Viagra or Revatio, both of which contain sildenafil as an active ingredient, should only be used in the approved indications and always under the supervision of a physician," the rep tells us.

Of course, Viagra is known to help men in another department ... which is why Scott's comment on ESPN's "Get Up" earlier this week had folks buzzing.

Scott's advice to Allen -- who has a history of not performing well in cold weather -- directed the QB to take the blue pill before the game against the New England Patriots to get his "circulation going."

"Take some Viagra before the game, baby," Scott said, much to the chagrin of his colleagues. "That'll get that circulation going right."

"Viagra was first a heart medicine, right?," Scott added. "So, it builds up circulation, which makes sure it gets circulation to the feet."

Allen -- who admittedly has bad circulation which leads to cold feet -- has had one of the worst completion percentages in the NFL over the last 15 years in freezing temps.

FYI, the forecast for the Bills-Pats game isn't doing Buffalo's star any favors -- the weather is expected to be in single-digits with a wind chill around -10 degrees.

Scary moment for professional skier George McQuinn who was knocked unconscious after a brutal crash during the FIS Freestyle World Cup event in Deer Valley Utah on Thursday.

But thankfully, he's okay.

The terrifying incident was caught on video ... showing the Team USA skier taking a nasty spill on the last jump of the course, smacking the back of his head as he took off.

McQuinn is immediately knocked out cold from the blow to his head, and you see his body go limp, as he then slides down the mountain, face first.

Medical professionals quickly jumped into action and removed McQuinn on a backboard from the course. Thankfully, officials announced shortly after the crash that he'd regained consciousness.

Later that night, McQuinn let his fans know that he was okay after the "gnarly crash" -- posting video of the incident on his IG and a photo of his facial injuries with a thumbs up.

For the first time ever, surgeons transplanted a heart from a genetically modified pig into a human patient, in order to save his life ... If all goes well, this could be the start of life-saving treatment for many patients in dire need.

57-year-old David Bennett received a heart like no other ... He was ineligible for a human transplant and, while doctors couldn't guarantee the transplant would work, the surgery was a matter of life or death, so he rolled the dice.

“It was either die or do this transplant. I want to live. I know it’s a shot in the dark, but it’s my last choice,” he said before undergoing the 7-hour surgery Friday at a Baltimore hospital.

The FDA had approved the operation for emergency use, since David had no other options.

Though it's still unclear if the transplant will actually take, he seems to be doing well days after the surgery... And, docs at the University of Maryland Medical Center say his transplant showed a heart from a genetically modified animal can work inside a human body without immediate rejection.

That's great news, because in the past such transplants failed because the patient's body would reject the animal organ. Now, Maryland surgeons used the heart from a pig that had received gene-editing ... to thwart rejection.

Naomi Osaka announced she's pulling out of the semi-finals of an Australian Open warm-up tournament after she says her body went into "shock" from playing hard tennis ... after she took months off to focus on herself.

Now, the Australian Open -- already possibly without superstar Novak Djokovic -- could also be without one of women's tennis' biggest stars, Osaka.

Naomi, clearly bummed, announced she was withdrawing from the Melbourne Summer Set over an ab injury.

“I had a lot of fun playing here in Melbourne,” Osaka said in an official statement. “Unfortunately I have an abdominal injury which I need to rest and prepare for the Australian Open.”

Osaka expanded on the injury on social media, tweeting her body "got a shock from playing back to back intense matches after the break she took" ... forcing the former No.1 ranked women's tennis player to pull out at the last minute.

As we previously reported, Naomi returned to the tennis court in November ... after stepping away from the game to focus on herself following an emotional loss at the U.S. Open in September.

Osaka -- a four-time Grand Slam singles champion -- has been outspoken about her struggles with mental health in the past, infamously boycotting the media at the French Open.

And now, 24-year-old Osaka -- who was scheduled to play Veronika Kudermetova of Russia -- is sidelined once again ... as she tries to rehab her way back to competition.

It's a cold, cold world out there ... and it got even chillier for a handful of skiers in North Carolina, who got hosed down with freezing water while already in below-freezing temps.

Check out this insane video that was captured Friday on the Beech Mountain Resort, where officials say someone slammed into a water/air hydrant while coming down the slopes during snowmaking operations ... and apparently knocked the whole thing off.

As a result ... an enormous amount of H2O was shot straight up into the air for a good long while through the waterline down below, creating a geyser effect on the ski lift passenger directly above.

Yes, a fair amount of them got drenched passing through ... but, for some reason, it looks like these poor guests got stuck right in the middle of the water -- getting absolutely drenched. Unclear how long they stayed in this position, but it was at least 30 seconds or so based on the video above, which was shot by a bystander.

Considering the harsh conditions, you can imagine these people were worse for wear afterward. Two guests were reportedly taken to the hospital with non-life-threatening injuries ... and some people are reported to have been blown off the chair lift altogether.

JoJo Siwa chatted with a 5-year-old cancer patient before surgery ... telling her everything would work out and she would kick cancer's butt.

As you see in the conversation between JoJo and Blakely Bergenfeld ... JoJo's a pro at putting her young fans at ease ... patiently answering the little girl's questions.

Blakely's parents, Jason and Kimberly Bergenfeld, tell TMZ ... the cancer diagnosis was sudden, after the little girl began experiencing headaches and fevers during a recent family ski trip.

We're told Blakely's parents took her to a pediatrician when they got back to L.A., and the doctor noticed her liver was swollen and rushed her to the ER at L.A. Children's Hospital.

Blakely's dad says his daughter underwent a series of tests, and that's when doctors discovered cancer in her kidney. She underwent surgery to remove a giant tumor on her kidney Friday.

We are told the surgery went even better than planned. She had to have her kidney removed because it was close to rupturing and would have been terminal if they had not treated it in time. The doctors also found tumors on her liver and lungs, which were removed. The doctors will know in the next few days exactly what stage and type of cancer she has, but she is stable and past the first step on her road to recovery.

It's been a whirlwind few days ... we're told Blakely had appeared completely healthy before she started feeling ill.

JoJo got involved after learning of Blakely's diagnosis through 'Dance Moms' star Kira Girard and her husband, who are close friends with the Bergenfelds.

Blakely is a huge JoJo fan and was supposed to meet her at the Nickelodeon awards last March before it was canceled due to COVID.

AEW star Rey Fenix suffered a horrific arm injury in the middle of his match Wednesday night ... and -- **HUGE WARNING** -- the video of the incident is extremely graphic.

Fenix was wrestling against Jungle Boy and Luchasaurus in a tag-team event with his partner, Penta Zero Miedo, at AEW Dynamite ... when the gruesome injury occurred.

Luchasaurus slammed Fenix through a table -- and as the two wrestlers hit the ground, Fenix's arm got caught in an awkward position and snapped backward.

Fenix was in an extreme amount of pain -- video from the ringside angle shows he was screaming loudly after hurting the arm.

The 31-year-old was unable to finish the match -- and he was reportedly rushed to the hospital.

No word on his condition today ... but we've reached out to AEW for comment.

Jungle Boy and Luchasaurus, meanwhile, went on to win the match as AEW personnel tended to Fenix. Jungle Boy (Luke Perry's son) tweeted afterward he hoped the star's injury wasn't too bad.

"Wishing a speedy recovery to @ReyFenixMx," the wrestler wrote. "One of the very best in the world, and one of the greatest people. It’s always an honor to share the ring with you. Much love."

Fenix is one of AEW's brightest stars -- he's known for his high-flying aerial moves, and he's a big-time crowd favorite.

Get well soon.

The Tampa Bay Buccaneers have formally released Antonio Brown ... and in announcing the news, the team called its former star a liar.

The Bucs said in a statement after officially cutting the wideout that he never indicated to their medical personnel that his ankle was too hurt to play in Sunday's game against the Jets.

Brown, of course, said the opposite in a lengthy statement Wednesday night ... claiming he did tell the team he was too injured -- and that head coach Bruce Arians still wanted him in the game nonetheless.

"While Antonio did receive treatment on his ankle and was listed on the injury report the week leading up to last Sunday's game, he was cleared to play by our medical team prior to the start of the game," the Bucs said Thursday.

"And at no point during the game did he indicate to our medical personnel that he could not play."

The Bucs went on to say that they've asked Antonio several times this week to be evaluated by "an outside orthopedic specialist" ... but say Antonio "has not complied."

"Maintaining the health and wellness of our players is of the utmost importance to our organization," the Bucs said.

As we previously reported, Brown melted down on the sidelines of the Bucs' game against the Jets at MetLife Stadium, stripping off his pads and shirt before running into the locker room.

After the blowup, Arians suggested that Brown had quit on the team ... telling Jay Glazer that he tried to get the wideout to go into the game multiple times, but AB refused and then left.

Brown, though, said Wednesday that's not the way things went down ... writing in a statement, "I took a seat on the sideline and my coach came up to me, very upset, and shouted, 'What's wrong with you? What's wrong with you?' I told him, 'It's my ankle.' But he knew that."

"He didn't call for medical attention," Brown added. "Instead, he shouted at me, 'YOU'RE DONE!' while he ran his finger across his throat. Coach was telling me that if I didn't play hurt, then I was done with the Bucs."

Arians previously said this week that Brown did not indicate to him at the time that he was hurt.

"I didn't quit," Brown insisted in his statement. "I was cut. I didn't walk away from my brothers. I was thrown out."

Brown says on Monday he saw a specialist, who told him that his ankle injury was so bad, it'll require season-ending surgery.

"What they did know until now is that on Monday morning I had an urgent MRI on my ankle," Brown said. "It shows broken fragments stuck in my ankle, the ligament torn from the bone, and cartilage loss, which are beyond painful. You can see the bone bulging from the outside."

Brown is now a free agent ... and he said Wednesday night he has no plans to retire.

"Once my surgery is complete, I'll be back to 100% and looking forward to next season. Business gonna be BOOMIN!"

Scary moment for Raheem Mostert -- the NFL running back's 3-year-old son was rushed to the hospital after suffering a high fever and other severe COVID-19 symptoms this week ... but thankfully, he's recovering back home.

The 49ers star's wife, Devon, shared the terrifying news on Wednesday ... posting a photo of their son, Gunnar, in an ambulance.

"If you think COVID is a joke, this is our sweet G man in an ambulance today after I called 911 because he was lethargic, skin was gray, lips were purple, and had a 103.5 temperature," Devon said.

"I'm crying even typing this ... this is all SO SCARY."

The good news is Gunnar is back home with his family ... but Mostert -- who is currently on the Niners' injured reserved list -- made it clear people should not be taking this virus lightly.

"I could say a lot, but I'm going to keep this short because my family gets 100% of my time right now," the 29-year-old said.

"Take COVID seriously! It's not a joke!!"

Raheem and Devon got married in 2017 and have 2 kids -- Gunnar and 1-year old Neeko. The couple also just announced they're expecting a third baby on the way last week.

Antonio Brown is finally addressing the bizarre incident that ended his Bucs career ... claiming the team gave him a "powerful and sometimes dangerous painkiller" and forced him to play despite knowing he had a serious ankle injury -- all leading to the moment he says head coach Bruce Arians told him "you're done!"

That's when 33-year-old AB says he removed his jersey and pads ... and walked off the Met Life football field.

"Because of my commitment to the game, I relented to pressure directly from my coach to play injured. Despite the pain, I suited up, the staff injected me with what I now know was a powerful and sometimes dangerous painkiller that the NFLPA has warned against using, and I gave it my all for the team," Brown said in a statement released by his attorney.

The 7x Pro Bowler continued, saying he balled until the pain got to a point where he could no longer endure it.

"I played until it was clear that I could not use my ankle to safely perform my playing responsibilities. On top of that, the pain was extreme. I took a seat on the sideline and my coach came up to me, very upset, and shouted, 'What's wrong with you? What's wrong with you?' I told him, 'It's my ankle.' But he knew that."

Unfortunately for AB, he says Arians didn't care, and demanded he go back in the game.

Brown says he responded ... '"Coach, I can't.' He didn't call for medical attention. Instead, he shouted at me, "YOU'RE DONE!" while he ran his finger across his throat. Coach was telling me that if I didn't play hurt, then I was done with the Bucs."

Bottom line, Brown says ... "I didn't quit. I was cut. I didn't walk away from my brothers. I was thrown out."

As for the Bucs, Arians claimed he never discussed an ankle injury with Antonio.

Clearly, AB and the team have two different views as to what transpired on the field ... in what was one of the strangest and surreal moments in NFL history.

If you missed the incident ... the defending Super Bowl champion Buccaneers were trailing the lowly NY Jets in New Jersey Sunday afternoon.

Brown -- who'd caught 3 balls for 26 yards -- was seen engaged in a very animated conversation on the sideline with star WR Mike Evans.

Then, AB, standing only feet from his teammates, removed his jersey, pads, and t-shirt until he was bare-chested. Brown threw his shirt into the stands ... and ultimately walked through the tunnel into the locker room.

Antonio was seen calling an Uber from the front of the stadium in East Rutherford, NJ ... before taking a car to NYC.

While in Manhattan, Brown says he saw several top doctors ... and was diagnosed with a significant ankle injury.

“What they did know until now is that on Monday morning I had an urgent MRI on my ankle. It shows broken fragments stuck in my ankle, the ligament torn from the bone, and cartilage loss, which are beyond painful. You can see the bone bulging from the outside.”

Antonio says the damage can be fixed ... but will require surgery, which he intends to have done.

As for his football future ... #81 says he plans to play again next year.

“Once my surgery is complete, I’ll be back to 100% and looking forward to next season. Business gonna be BOOMIN!"

Question is ... will there be any takers?
