Travis Scott's pulling out of a big music festival in Las Vegas this weekend ... seemingly because he needs more time to heal his injured knee.

The rapper just announced he won't be able to make it for his headlining gig at Day N Vegas -- which is going down at the Las Vegas Festival Grounds Friday through Sunday.

Scott apologized on Twitter to all the ragers planning on attending, saying he's unable to "pull up" but promises to be back soon.

Trav was set to take the main stage on Saturday, but now that honor goes to Future x Metro Boomin. J Cole's headlining Friday and Kendrick Lamar on Sunday.

We broke the story ... Travis suffered a dislocated knee while performing earlier this month at NYC's Rolling Loud Fest. He landed on his leg awkwardly as he was jumping up and down during a song, but popped up and finished the show nonetheless.

All signs pointed to him having surgery to fix the injury, but it's unclear if he ever did or just needs more time to recoup naturally.

Trent Williams says Washington Redskins doctors misdiagnosed his cancer more than FIVE YEARS ago ... and the 7-time Pro Bowl left tackle says it nearly cost him his life.

The 31-year-old -- who held out from the team earlier this season -- returned to the Redskins this week ... and in his first meeting with reporters, he made the stunning revelation.

Williams claims back in 2013, he approached team doctors about a growth on his head ... but says after they told him it was a benign cyst and nothing to worry about, he essentially ignored it.

But, Williams says the tumor kept on growing ... and when he finally went to have it checked out by independent doctors this year -- they told him it was a serious form of cancer.

"[They] told me it was DFSP," Williams said, referring to Dermatofibrosarcoma Protuberans. "That's what the cancer is called. It's a very rare soft tissue cancer."

Williams said the form of cancer was so serious, "I almost lost my life" ... and added, "I was lucky."

The 6-foot-5, 320-pound offensive lineman said he needed multiple surgeries -- including one where surgeons extracted the tumor from his skull -- to fix the issue.

Williams says other than some lingering effects on his scalp due to the surgeries, he's relatively fine now ... but he says he's having some serious difficulties trusting the Redskins.

Williams says the alleged misdiagnosis from team doctors is the reason he's been away from the 'Skins this season ... and he didn't seem sure if he'd ever play for the team again.

"Seriously, I almost lost my life," Williams said. "You're 30, coming off your seventh straight Pro Bowl and a doctor tells you to get your affairs in order."

"It's not going to sit well with you. And, it still doesn't."

R. Kelly's officially got problems from head-to-toe -- an infection on one of his little piggies forced him to miss a date ... with the judge.

The singer's lawyer, Steven Greenberg, says Kelly was absent from federal court in Chicago Wednesday because he had an infection that required his toenail to be removed.

Kelly was worried someone would step on his ailing tootsie if he appeared in the courtroom ... according to Greenberg. He adds that Kelly is in a walking boot as he recovers from the infection and procedure.

As for the hearing ... it was mostly procedural and just the lawyers for both sides were present -- no defendants were there either. The next hearing was scheduled for February.

The case is one of several sexual assault cases against Kelly ... he's also facing federal charges in New York and has state cases in Illinois and Minnesota.

No word if any future hearings for any of those cases will be impacted by the, umm ... bump and grinding of his toenail. Nasty.

Kevin Hart is speaking out and giving fans a glimpse into his road to recovery for the first time since sustaining a serious back injury in his L.A. car crash.

Hart -- who underwent back surgery -- after the early September crash holds little back in a video posted Tuesday night. He shows scenes of himself in a hospital bed, being assisted by nurses and using a walker just to stand up.

Throughout the video, Kevin slowly regains his strength ... revealing his intensive physical therapy routine ... with everything from weight training to pool workouts.

Kevin also talks throughout the video ... sharing a powerful message of determination. He states he believes the accident was God's way of telling him to slow down, and appreciate life for what it really is.

He also takes the time to thank his family, friends and those who have stood by him through it all ... saying, "My appreciation for life is through the roof," and, "Don't take today for granted, because tomorrow is not promised."

The video concludes with a scene of Kevin chatting with one of his doctors who tells him it'll be about a year for a full recovery, but judging by what Kevin's done already ... it seems he's well on his way.

UFC star Derrick Lewis says he doesn't mind watching men bleed in the Octagon -- but he gets squeamish when it comes to bloody women because it makes him think of messy periods.

The 34-year-old heavyweight spelled it all out on "Bernie & Sid in the Morning" -- saying, "I really don't like watching women fights."

When pressed on the issue, Lewis explained ... "Last week, I finally had thought I forgot they had periods. I wonder if they still fight on their period?"

Lewis continued ... "You would think they get cut in the face, something like that [and] they're bleeding and stuff like that ... but no, it's from them being on their period."

"So, I don't like watching women fight."

For the record, this has NEVER been an issue in the UFC or any other pro-MMA or combat sports organization, as far as we know.

Chargers reinforcements might not be on the way after all ... Derwin James tells TMZ Sports he's not sure yet if he'll be able to return from a foot injury this season.

"I don't know, man," the stud safety says. "I just got to keep healing and we'll see what happens."

Derwin -- who's one of the game's brightest young defensive players -- has been out since the summer after he needed surgery to fix a foot he busted up back at Florida State.

The 23-year-old was put on injured reserve and was expected to make a return sometime this season ... but now, he doesn't seem entirely sure that's going to happen.

In fact, when our camera guy asked if Derwin would be able available for either game against the Chiefs this year (one is Nov. 18, the other is Dec. 29), he said, "You gotta see. Tune in."

It ain't like James has suffered a setback or anything ... in fact, when he was out promoting phone company ROKiT in L.A. on Tuesday, he showed no signs of a limp and was having a blast.

It just seems like the dude's trying to get back to 100% ... telling us, "Feeling good, getting better, man. Getting healthy. Trying to get back out there."

Alex Trebek feels he found out about his own pancreatic cancer too late, and he doesn't want others to do the same ... so he's out campaigning to raise awareness.

The "Jeopardy!" host released a PSA Wednesday, announcing a partnership between him and the World Pancreatic Cancer Coalition ... in which Alex has vowed to help spread the word across the globe on the risks and symptoms of the often-deadly disease.

The reason ... the fact that pancreatic cancer is the only major cancer with a 5-year survival rate in the single digits in nearly every country, more than enough reason to get behind this cause -- is it sounds like Alex wants to help folks try and get ahead of it.

He says it rather matter-of-factly here ... he himself wishes he'd known sooner, and realized that the persistent stomach pains he felt prior to his official diagnosis were a symptom.

There are other symptoms too, that Alex outlines here ... mid-back pain, unexplained weight loss, new-onset diabetes and the yellowing of the skin and eyes, among others.

Trebek is asking for the public's help with his newfound campaign, asking people to wear purple on World Pancreatic Cancer Day ... which falls on November 21. Of course, Alex is in the middle of his own cancer fight after announcing his diagnosis earlier this year.

He's currently undergoing a second-round of chemotherapy, and has suggested he would step away and give up his hosting duties if his skills start to diminish noticeably.

Luckily for him (and viewers) ... we're told there's no sign of that happening anytime soon.

Kanye West has his facts messed up when it comes to Plan B and abortion -- two things he mistakenly thinks go hand in hand.

A rep for Foundation Consumer Healthcare -- the pharma company that makes the Plan B One-Step contraceptive -- tells TMZ that their pill is in no way connected to the process of abortion ... even though Ye appeared to conflate the topics.

You'll recall ... Kanye mentioned Plan B and abortion in a rant he went on about the Democratic party, which he thinks has brainwashed African-Americans into killing babies.

That is simply NOT the case though, when it comes to Plan B ... so says FCH. The company tells us plainly, "Plan B emergency contraception is a safe and effective backup option when used as directed after unprotected sex or birth control failure." Hmmm ... go on.

They add, "Plan B helps prevent pregnancy before it starts by delaying ovulation. Plan B is not an abortion pill – it will not harm an existing pregnancy and it will not be effective if a woman is already pregnant." In short, it ain't an abortion pill, despite misconceptions.

A rep for Planned Parenthood sounded off as well, saying black women have actually had a leading role in the fight for abortion access, sex education and reproductive health rights.

The spokesperson adds, "As Black women, we make our own decisions about our bodies and pregnancies, and want and deserve to have access to the best medical care available. Misinformation like this is meant to shame us and keep us from making our own health care decisions. Black women want and deserve support and access to the full range of reproductive health care, but this persistent lie is threatening our ability to obtain it."

Kevin Hart appears to be sparing the driver of a nasty car wreck that nearly killed him  -- because we've learned he isn't planning to take the guy to court.

Sources close to the comedian tell TMZ ... Kevin does not intend to sue driver Jared Black, whom the CHP determined caused the crash by driving recklessly. In fact, we're told Kevin's not even going to file a claim with Jared's insurance company to cover his medical bills and the cost of the 1970 Plymouth Baraccuda, which was totaled in the single-car crash.

Our sources say Kevin likes Jared and Jared's fiancee is close to Kevin's wife, Eniko. The fiancee, Rebecca, is Eniko's personal trainer.

We're told Kevin will use his personal health insurance to cover medical costs. It's not like he needs the money. It's unclear whether he's just going to write off the value of the car.

The medical bills are going to be huge. Kevin had surgery for 3 fractures on his back and is undergoing intensive therapy. All of that put the medical bills in the stratosphere.

Here's the kicker... we're told that Jared himself has lawyered up, and could file suit against Kevin for not having the proper safety harnesses in the car. If he does sue, there's a problem, because no one in the car was even wearing their safety belt. So, even if there were harnesses, it wouldn't have done anyone any good if no one strapped in.

If Zion Williamson wants to cut out injuries and cut weight ... he NEEDS to cut meat out of his diet ASAP, so says John Salley who says VEGANISM can save Zion's career.

Look, a lot of people think 284 pound Zion is just too heavy to have a long NBA career. He's already missing the first 6 to 8 weeks of the NBA season after undergoing knee surgery.

Enter Salley ... who says Zion can turn the ship around if he turns his diet around.

"My message to Zion? Go vegan, bro. Drink a bunch of water and find out the best way to heal your body, meaning ... not just ultrasounds, not just a hot tub, don't take pills."

The 4-time NBA champ says Zion was destined to become teammates with Jahlil Okafor, who recently made the switch to "mostly" veganism and lost 20 pounds ... and Salley wants Williamson to listen to the vet.

Kanye West has an interesting situation ... he's planning on a concert tour of sorts -- taking his wildly popular Sunday Service on the road -- but can he get an insurance company to cover the tour if disaster strikes like it did 3 years ago? Well, we found out he can, but there's a catch.

We've contacted Kanye sources as well as sources in the insurance industry, and here's what we know. Kanye can get his tour insured, but the insurance company will not cover cancellations due to mental health issues.

TMZ broke the story ... Ye pulled the plug on his Saint Pablo Tour back in November 2016, hours before he was supposed to take the stage in L.A. He was hospitalized at UCLA for 9 days to treat some pretty serious issues.

Kanye, who has said in the past he's bipolar, told us he was off his meds because they made him feel bad.

So, given that backdrop, we're told the major companies that insure concert tours would not cover hospitalization due to mental health issues ... and it doesn't matter if Kanye is taking meds or not. There will be no coverage.

That said, we're told insurance companies will still underwrite a policy for his tour with that exclusion.

Kanye has already said he's ready to get started with the JIK tour "right away," and it seems folks got a taste of what it'll look like this weekend at The Forum. Point being, he'll probably have to decide on an insurer pretty soon here if he wants to keep his word.

The Milwaukee Brewers will have their MVP back to start next season ... Christian Yelich tells TMZ Sports his fractured knee cap is now feeling 100% healthy!!

"I'm doing great, man," Yelich says. "All good."

The superstar outfielder busted up his knee back on Sept. 10 when he fouled a pitch off his right leg ... and there was initial concern the injury could linger into next season.

But, Yelich -- who ultimately didn't require surgery to fix the issue -- told us out at LAX he's feeling great ... and expects to be good to go for the start of spring training in a few months.

"We're ready to go, man," Yelich says.

Of course, that's great news for Milwaukee ... Yelich is maybe the best player in the MLB -- and could win his second straight National League MVP award next month.

By the way, Christian also gave us more good news ... telling us he and his family haven't been affected by the wildfires that are raging near his Thousand Oaks, Calif. hometown.

Skateboarding superstar Nyjah Huston was totally stoked to see video of a 7-year-old boy with cerebral palsy hitting the ramps with his mom ... telling TMZ Sports the clip is "awesome!!"

As we previously reported ... Avante Leaozinho -- who was diagnosed with cerebral palsy at 18 months -- had the time of his life as his mom pushed him around the skate park ... and the video quickly went viral.

We showed the touching vid to the 24-year-old X Games champ outside Halsey's Halloween party over the weekend ... and Nyjah couldn't get enough of it.

"That's awesome," Huston says. "I love seeing stuff like this, that's amazing!!"

"I always love seeing people be down for skating, no matter what the circumstances are."

As busy as he is, Alex Trebek made time for kindness in the smallest of acts ... helping lift the spirits of an autistic man whose mom was determined to get Alex on the horn.

This story's bound to tug at your heartstrings. Pulmonary fibrosis survivor Debbie Stevens attempted to move mountains to have her 32-year-old son, Michael Kneeter, have a chat with the longtime 'Jeopardy' host after he learned Trebek was diagnosed with pancreatic cancer.

Michael, who's autistic, had become depressed and withdrawn ... so his mom hopped online to see if she could track down Trebek. She ended up connecting with his son instead, and made the pitch of her life to see if Alex could squeeze in a call to Michael.

Lo and behold, Trebek called!!! Unfortunately, Debbie and Michael missed his call and got a voicemail instead. Devastated, Debbie reached out to Trebek's son again in a last-ditch effort to talk, and sure enough ... Trebek called again and got them.

According to the NY Daily News ... the trio talked for about 10 minutes, with Alex expressing his deepest thanks to Michael for being a fan. Debbie says Alex told them he wouldn't be stepping away from hosting 'Jeopardy' anytime soon and would keep fighting.

Ben Affleck seemed to have fallen off the wagon Saturday night at a Halloween party.

Ben was leaving La Peer Hotel in West Hollywood for the Unicef Masquerade ball. He clearly has trouble walking and uses the SUV to steady himself. He nearly fell before catching himself on the vehicle.

Affleck has had a rough go of things over the years. He's struggled with his sobriety and repeatedly gone to rehab ... most recently in August 2018, when his ex-wife, Jennifer Garner, drove him to a facility in Malibu. He's had a sober coach and seemed to have been doing well.

Ben had been attending wellness classes at an L.A. wellness center that specializes in "Buddhist ethics," where people who attend engage in meditation with a focus on healthy body, mind and spirit.

Sobriety is difficult and elusive for everyone struggling with addiction, and we're told Ben has acknowledged he's going to slip up from time to time ... it was never as if this was simply behind him.

It's unclear if Ben will be heading back to rehab.

Randy Couture is so damn tough ... HE WALKED HOME FROM THE HOSPITAL AFTER SUFFERING A HEART ATTACK!!!

Just 2 days after the 56-year-old UFC Hall of Famer suffered a heart attack and underwent an emergency procedure ... Couture walked out of Cedars Sinai under his own power.

Couture, clutching an adorable oversized stuffed animal, was surrounded by his family and friends as he walked home Friday ... and told TMZ Sports all about the experience.

"Feeling good, way better obviously," Couture said ... admitting the health scare was a reality check about mortality.

"At some level, you think you're invincible and then you find out you're not."

The good news, Couture says doctors have identified the problem and he'll be following up with specialists to make sure this never happens again!!!

Couture says he's already itching to get back in the gym and resume training with his MMA pals ... but knows he should take it slow. Good luck stopping this man.

Oh, and he's already planning to get back to work in Hollywood -- telling TMZ Sports he's got a shoot for a new movie with Michael Jai White on Tuesday and he ain't missing it!!!

There's more ... Couture says he was overwhelmed by the outpouring of support from close friends and old rivals ... including Chuck Liddell and Tito Ortiz, who both reached out.
