Nurse!

Cops in NYC are looking for a man after this horrifying video surfaced of the guy throwing a woman onto subway train tracks -- an act of violence authorities are calling totally unprovoked.

This attack went down Sunday in the Bronx -- the video shows a guy grab a lady by the shoulders and shove her down to the ground, off the subway platform and onto the tracks. Chillingly, he casually walks away from the scene.

Law enforcement sources tell us the shove seems to have come out of nowhere, for no apparent reason ... and the woman suffered a broken collar bone and lacerations to her head.

NYPD is asking for assistance in identifying the man, who's so far gone uncaptured.

After the attack, the man is said to have fled without further incident, and people standing nearby helped the woman off the tracks. She was taken to a hospital in stable condition.

Terrifying moment involving a professional boxer in South Africa ... the previously unbeaten fighter became disoriented and started punching air, as if he saw a fighter that didn't exist.

Video of the incident hit social media on Sunday ... showing Simiso Buthelezi fighting Siphesihle Mntungwa for the WBF African lightweight title. In the 10th round of the fight, Simiso was easily winning, when something went very wrong.

A few seconds into the final round, Mntungwa falls through the ropes. When he gets up, the ref tells the men to continue fighting.

However, Buthelezi turns to the referee, and squares up to him, as if he is the opponent. Seeing this happening, the ref shuffles to the side.

Buthelezi then advances to the corner of the ring and starts throwing punches at the air ... as if he were fighting an invisible opponent.

The ref did a great job, sensing something was wrong ... and immediately ended the fight.

Buthelezi was taken to a local hospital where he is reportedly in stable condition.

As for why he had the reaction he did ... that's currently unclear.

Most importantly ... get well soon, Simiso.

Cody Rhodes is built different ... the son of WWE Hall of Famer, Dusty, defeated Seth Rollins in a "Hell in a Cell" match after tearing his pectoral muscle earlier in the day.

WWE announced the news on its "Hell in a Cell" kickoff show ... saying Cody had his right pectoral tendon "completely torn off the bone while weight training."

Still, the 36-year-old wrestling star proceeded to fight Seth ... inside, arguably, the most dangerous match in WWE history.

As the match was about to start, Rhodes took off his robe ... showing off the gruesome injury.

Fans were astonished at how bad Rhodes' injury appeared -- his pec was severely discolored and jarring to the eyes -- but that didn't stop Rollins from laughing at the injury and targeting the area during the match.

Cody even took a kendo stick right on the pec ... leaving him writhing in pain (maybe part of the show, maybe not).

Regardless, fans were super appreciative of Rhodes ... and gave him a standing ovation for the tenacity and resiliency after delivering 3 Cross Rhodes finishers to secure the victory.

Bodybuilding star Calum von Moger just revealed some of the injuries he suffered in a near-death fall last month ... showing he was battered, bruised, scarred and deeply cut on nearly every part of his body.

Posting on his social media page this weekend for the first time since he reportedly crashed through a second-story window in early May ... von Moger showed his body went through hell.

In a video the 31-year-old took from his hospital bed, you can see he required stitches to close wounds on his hands and arms, and also needed bandages all over as well.

von Moger, who reportedly suffered a spine injury in the fall that was so severe it had him in a medically induced coma, also showed a photo of a huge scar on the middle of his back.

"What waking up from a bad dream looks like..." he wrote in the caption on the video.

von Moger added that "it's nice to be alive" ... and thanked all his fans for their "well wishes and prayers" while he was in the hospital.

von Moger, according to reports, returned home from the medical facility in late May -- a few weeks after the fall -- and he was reportedly seen there walking without any assistance.

The former Mr. Universe, who also played a young Arnold Schwarzenegger in the '18 flick "Bigger," did say in an Instagram story, though, that he still has a "long road ahead to recover from this one."

Danielle Kang, one of the world's best golfers, revealed she's been playing in the U.S. Women's Open with a tumor on her spine.

The 29-year-old made the shocking revelation on Friday ... saying she received the diagnosis from doctors "a few weeks ago."

Kang -- the #12 player in the world -- said she's undergone extensive testing, and is waiting for doctors to tell her if the tumor is benign or malignant.

"I’ve gone through a lot of procedures so far, and with the process of elimination, we are narrowing it down,” she said Friday. "It’s going to take time."

It's been a rough few months for Kang -- she's been dealing with back pain, which forced her to withdraw from the Lotte Championship in early April. She also pulled out of the Palos Verde Championship later that month.

The golf sensation is optimistic doctors will be able to tell her the condition of the tumor ... and identify whether it's the source of the pain in her back.

Despite the health scare, Kang had her sights set on finishing out the week in hopes of making the cut ... but admits she's not feeling "fantastic" out there on the course at Pine Needles Lodge and Golf Club in San Francisco.

"My goal right now is to get through this week," Kang said. "I wanted to make the cut. I wanted to play four rounds out here and then my focus was going to be getting better after that."

"The only thing on my mind has been to play the U.S. Open."

The epic French Open match between Rafael Nadal and Alexander Zverev came to an unfortunate halt on Friday ... after the German star was forced to retire due to a gruesome ankle injury.

The semifinal showdown had all the makings of being a classic -- Rafa won the first set in a tiebreaker ... and as Rafa positioned himself to force another tiebreaker, Sascha's ankle rolled and he fell to the clay.

Zverev screamed and writhed in pain ... as Nadal came to his side in support.

As it turns out, NBA star Kevin Love was in the stands at Roland Garros ... documenting the heartbreaking scene on his Instagram.

The 25-year-old was taken off in a wheelchair ... and eventually came back out on the court on crutches to officially retire from the match. The crowd cheered as he waved to the fans.

Nadal praised Zverev in a post-match interview ... and gave the #3-ranked pro a hug.

A fitness trainer tried to do his best LeBron James impression at the King's "Hustle" movie premiere on Wednesday -- attempting to throw down a sweet dunk -- but he came up just short on the landing, and broke his tooth on the hoop's stanchion!

Quan Bailey was on hand in L.A. for the screening of LBJ's new flick -- which stars Adam Sandler -- and he decided to show off on a makeshift court set up near the Westwood Regency Village Theatre.

Bailey threw down one dunk with ease ... but as he finished another alley-oop one, he misjudged his landing -- and slammed his face on the structure holding up the rim!

Bailey immediately knew something was wrong ... grabbing at his grill, before realizing he had a bloody lip and a broken tooth.

Bailey, though, was a good sport about it all ... and even joked on his social media page afterward, "First man to break a tooth at a Hollywood movie premiere ... That one hurt lol."

Bailey said on Thursday morning his mouth was still in pain, but he managed to get some training in ... and added that he's trying to get to a dentist to fix the tooth later in the afternoon.

Josh Allen shanked a ball so badly during Wednesday night's 'The Match' -- he drilled a fan in the back of the head ... but, thankfully, the guy somehow wasn't severely injured.

The wayward tee shot happened on the sixth hole of the event at Wynn Golf Club in Las Vegas ... when Allen pushed his ball some 20 yards to the right of the green.

In video of the swing, captured by John of @BackNineBullies, on the 190-yard par 3, you can hear the ball crashing down right on a spectator's noggin.

The fan immediately crumpled to the ground in pain, yelling out, "Wow! I got it! Oh, my God!" ... although, fortunately, he ended up ultimately being all right.

Allen eventually made his way up to the fan ... and apologized repeatedly for the shot -- and signed a golf ball, a glove and a football as a mea culpa.

We're told the spectator needed some ice and had a big bump on his head -- but he appeared to finish up the event just fine.

As for Allen, his game never quite looked good during 'The Match' -- he nailed fans continuously throughout the round -- and he and Patrick Mahomes went on to lose to Aaron Rodgers and Tom Brady.

Bam Margera's fall at a skate park -- which has his wrist currently in a cast -- was painfully and very clearly captured on video newly obtained by TMZ ... and just watching the wipeout is gonna make ya go ... ouch!!!

Bam's tumble went down at the Hobbit Skate Park in Delray Beach, FL ... as you can see, the trick he tried to land didn't work out as planned, slamming him to the ground, right wrist first.

The "Jackass" star tells us it was a trick he hadn't tried in over a year, and it ended with his arm bending backward and bones nearly breaking his skin.

As we reported, Bam just completed 1 year of alcohol and drug treatment, so he's biting the bullet and refusing all painkillers as he recovers from the broken wrist.

Paulo Costa is breaking his silence on the allegations that he attacked a nurse in Brazil earlier this week ... saying in a statement on Wednesday the claims are "reckless and inconsistent."

The UFC star, according to Brazilian media outlet Globo.com, was accused of hitting a nurse with his elbow following an argument over a COVID vaccine card in Belo Horizonte.

The outlet reported that Costa told nurses he wanted a vaccination. But, according to the report, Costa backed out of getting the shots, yet still wanted the filled-out vaccine card.

Globo.com reported when a female nurse tried to stop him from leaving with the card, the 31-year-old hit her with an elbow. She reportedly complained of swelling in her lips.

On his Instagram page Wednesday, Costa opened up about the allegations ... saying in a statement, "The accusations and facts narrated do not reflect the reality of what happened."

"The fact will be carefully investigated and the appropriate legal measures for their perfect clarification will be taken."

He added in the press release, "this kind of allegations are completely incompatible with his history and way of life."

It's unclear if Costa is currently under police investigation.

The son of "90 Day Fiance" stars Deavan Clegg and Jihoon Lee has been diagnosed with leukemia.

3-year-old Taeyang was diagnosed with b-cell quite lymphoblastic leukemia last week -- a type of blood cancer that's more common in young children ... Deavan's publicist, Lindsay Feldman of BrandBomb PR, tells TMZ.

He's been in the hospital ever since and is expected to stay there a while ... he's already started chemo treatments and is awaiting further procedures. Deavan was told this will be a long two-year process, with a high success rate of full recovery in five years.

According to the GoFundMe page started by Deavan's mother, Taeyang took countless trips to the ER before a specialist told them he had cancer cells. The family is looking to raise $50K to cover expenses.

We're told Deavan attempted to contact Jihoon about their son's diagnosis but has been unsuccessful ... he has her and her family's numbers, emails and social media blocked. She even tried contacting Jihoon's father but was unsuccessful.

A viral video of a young woman getting beaten up has led the internet to believe it could possibly be Zendaya -- but based on the visual evidence we've seen ... it's likely BS.

This clip made the rounds this weekend ... it's 7 seconds long, and it shows somebody wailing on this poor girl inside of an apparent store somewhere. After they're done punching, they resort to kicking, sending the woman flying back and knocking her head against a wall.

Indeed, it's incredibly brutal -- and there's no context whatsoever, as far as we can see, that points to where or when this happened, who exactly was involved, or why.

What people do believe they see here, however, is someone who appears to resemble Zendaya -- at least from the quick glimpses of this girl's face you can make out in the video. Yes, we'll admit ... it does look a bit like the actress -- especially from her 'Euphoria' scenes.

Again, there's no telling when this might've been from -- or if it's even Zendaya at all, frankly -- but FWIW, Z isn't rocking this length of hair at the moment ... she's got a much shorter 'do right now, as you can see in recent pap shots of her out and about in Massachusetts.

Her shoe-wear is also different than what's in this video -- rainbow-colored Crocs. Zendaya's got sneakers on here ... and has publicly said she'll either rock tennis shoes or heels, not much in between. Zendaya's never been snapped in Crocs from what we could find.

The bottom line is this ... there's no clear evidence this is, in fact, Zendaya -- and yet, Twitter's got her trending right now since they think it could be her. Zendaya or not though -- others have pointed out that those who are mocking this are sending the wrong message.

Even if it's just a doppelganger ... the filming and recirculation of an assault on a woman of color is something many see as a disturbing trend -- with this just being the latest example.

We've reached out to Zendaya's camp for comment. She hasn't spoken up on this quite yet -- but if it isn't her, it might be worth debunking ... 'cause this thing is running rampant.

Ruby Barker, one of the stars of the massive Netflix hit "Bridgerton," has opened up about her mental struggles that have landed her in the hospital.

Ruby posted a video Thursday revealing her struggle, saying, "It's time to be transparent."

The 25-year-old didn't hold back ... "I have been really unwell for a really long time. I want to be honest with everyone. I have been struggling."

Ruby wasn't specific about where she's being treated, saying, "I am in hospital at the minute and I am going to be discharged soon and hopefully get to continue with my life."

Her message came during Mental Health Awareness Week in the U.K., so the timing is not coincidental ... "I am going to take a little bit of a break for myself and I would encourage others, if you are struggling, do yourself a favor and take a break. Stop being so hard on yourself."

Ruby explained what symptoms had manifested that made her aware she needed help, saying she was "rage-filled" with "intergenerational trauma bundled up inside me."

She went on... "I was carrying the weight of the world on my back and now I am at the point where I can have a diagnosis ... I can't carry on the way that I was. I need to change so that is what I am trying to do. I want to survive and I will survive. I am going to."

Soccer star Zlatan Ibrahimović says he went through hell the past six months while playing with "no ACL" in his left knee ... revealing Thursday he had "20 injections" in the leg and "never suffered so much."

The AC Milan superstar added the knee that he injured roughly one year ago required weekly drainage ... and he had to take painkillers daily in order to compete on the field with his squad this past season.

"I was only able to train with the team 10 times in the last six months," Zlatan said in a social media post Thursday morning.

"Barely slept for six months because of the pain. Never suffered so much on and off the pitch."

Zlatan, though, had the ligament repaired on Wednesday -- and despite his team saying he'd be out for roughly the next eight months -- he seemed to be in good spirits while reflecting on everything he did in 2022 to help his squad win the Serie A title.

"I made something impossible to something possible," said Zlatan, who was somehow able to score eight goals in 27 appearances this season despite the injury.

"In my mind I had only one objective, to make my teammates and coach champions of Italy because I made them a promise."

"Today I have a new ACL and another trophy."

A Celebrity Cruises passenger says her medical emergency while onboard became an absolute nightmare for her, because the ship's medics gave her a blood transfusion from someone who had HIV.

The woman was on a 7-day cruise that started Dec. 4, 2021, and on the 5th day she had to go to the medical center because she was suffering rectal bleeding ... and it was really bad. In a new federal lawsuit, she says the doctors diagnosed a gastrointestinal hemorrhage and she would need an emergency blood transfusion just to survive.

According to the suit, obtained by TMZ, the medical staff solicited blood from passengers ... announcing over the ship's PA system that they needed Type A-negative blood. The woman says 4 passengers stepped up to donate blood, and she got the transfusion.

Sometime later, she's not specific in the documents, the woman says she was diagnosed with HIV ... and she believes she got it from the transfusion. In her suit, she calls out Celebrity Cruises doctors for not properly screening the donated blood before pumping it into her.

The passenger is suing the cruise line for unspecified damages.

What's interesting is she says the cruise doctors told her she would have died without the transfusion. On the one hand, the doctors -- and her fellow passengers who donated blood -- clearly saved her life. However, she now has to live with HIV, which is very much treatable these days, but still incurable.

Jaromir Jagr -- one of the best NHL players ever -- says he's fortunate to be alive today ... after his car collided with a tram at a high rate of speed.

The Pittsburgh Penguins legend explained the terrifying accident in a post on his social media page Wednesday ... saying it was all his fault.

In his post, which was written in Czech, Jagr said he was trying to cross the road, and ultimately didn't see a tram that was coming at him at "high speed."

"I thought it was my end," the 50-year-old said.

In a photo of his car following the accident, you can see the tram hit Jagr's driver's side door -- leaving a huge dent. The hockey player, though, said he somehow escaped just fine.

"I climbed out without injury," he said.

According to Czech news website iSport.cz, authorities said Jagr's alcohol tests were negative.

"I thank everyone for their understanding," Jagr said, "and also for the help to those who intervened on the spot."
