Nurse!

There's new alleged video proof that supports a man's claim he was injured during a Jet Ski stunt gone wrong involving "Jackass" stars Steve-O and Chris Pontius.

TMZ broke the story, Michael Vicens-Segura is suing the veteran stuntmen for an incident he says, left him badly injured, suffering a gash on the side of his head.

In the video, you can see Vicens-Segura in the water between the vessels just before they take off, once the Jet-skis moved, Vicens-Segura was allegedly struck by the cable connecting the two when it snapped.

The aftermath is intense, and Michael is clearly in a lot of pain.

Michael says the whole thing happened in Puerto Rico in 2018 when the two guys and movie producers planned to do some kind of "Jet Ski Tug of War" ... which basically meant two guys would operate the jet ski in opposite directions.

Michael's attorney, John Phillips, now says ... "We provide this video looking for witnesses and people who know about the creation and execution of this stunt. If you have information, please contact us."

Vicens-Segura says he had to get a metal plate in his head and his life has been completely changed by the incident ... he is asking for more than $12 mil in damages.

Scary moment during a WWE NXT UK match Thursday ... Blair Davenport suffered a gnarly leg injury after she jumped off the top rope and landed on the ground awkwardly.

Davenport was competing against fellow wrestling star Meiko Satomura in a Japanese Street Fight for the NXT UK Women's Championship ... when disaster struck.

During the match, Blair climbed to the top of a ring post, jumped, and then slammed her feet onto the back of Meiko, who was outstretched on the apron.

But, when Davenport hit the ground just after that, you can see in video, her ankle and knee crumpled below her body.

Davenport was hurt so badly, she screamed in pain. The ref then immediately ended the match.

"This is really hard to see," one announcer said. "When any competitor gets hurt, regardless of how physical this match was, it's tough to watch."

Satomura -- the reigning champ -- looked concerned the entire time while Davenport received assistance from the medical staff.

Blair posted an update on her Twitter account following the match ... showing a picture of her on crutches and in a walking boot.

"Whoops😬 BRB ✌" she said.

Steve-O and Chris Pontius are responsible for a 'Jackass'-style water stunt that left a man with a busted up head and a ruined life ... at least according to a lawsuit filed by the guy who claims he was injured.

The veteran stuntmen are being taken to court by Michael Vicens-Segura, who says he was approached by them back in 2018 to see if they could use his jet ski for a project they were filming in Puerto Rico.

Vicens-Segura insists the guys wanted to use it for a 'Jackass'-y feat -- where 2 guys are in the water on jet skis, facing opposite directions ... and attached to one another by a bungee cord, to see who would get yanked off first as they sped off.

Essentially, it's a jet ski tug of war ... and Vicens-Segura says the 'Jackass' guys have done something similar in the past -- in their movie, no less. It was called the BMX Tug of War.

Now, per the lawsuit, filed by attorney John Phillips and obtained by TMZ, Vicens-Segura was asked to hold one of the jet skis steady in the water because of the waves that day ... which he says he did. He claims, as Steve-O and Chris hit the gas, Steve's bungee cord snapped off the harness attached to his back ... which he says then flung in his direction and popped him hard on the side of the head, resulting in a massive gash.

Vicens-Segura says he had to be helicoptered to a hospital for emergency surgery, and even needed to be placed in a medically induced coma because he had a fractured skull and brain bleeding, among other things.

After several medical procedures, Vicens-Segura claims he was left in bad shape as he recovered ... and also had some pretty gnarly scars. He claims he's lost his ability to work, to think straight ... and continues to experience pain, suffering and agony because of what happened to him.

Of course, he's blaming Steve-O, Chris and others for the whole thing ... suing them for negligence and moreover the alleged incident. He's asking the court for more than $12 million in damages.

Lisa Vanderpump's hubby, Ken Todd, says the 'RHOBH' star will likely never ride a horse again ... after her last ride ended with a badly broken leg.

We caught up with Ken on Tuesday, just as Lisa was having surgery to repair the shattered bones. Ken confirms she broke her leg in 3 places, and will have a bunch of new hardware by the time you're reading this.

He says he's not completely sure how long it will take Lisa to fully recover, but he's guessing about 8-10 weeks.

One thing at least he's sure of ... LV's riding days are over. Ken says the horse she was riding Sunday was a gentle and amazing animal, and despite the ol' saying, it doesn't sound like he wants his wife to risk it by getting back on the horse. Of course, we'll have to see what Lisa thinks once she's recovered.

As we've previously reported, the 'Real House Wives' star was riding in L.A. when her steed apparently got scared, reared up and bucked her off.

Ken saw it happen, and was in complete shock -- he says Lisa immediately knew something was broken.

Simon Cowell did it again ... he crashed his e-bike and landed in the hospital with broken bones.

Sources tell TMZ ... Simon was tooling around on the bike in London last Thursday when he turned a sharp corner ... or at least he tried to turn. The road was wet and the tires went out from under him and he crashed to the ground.

We're told Simon broke his left arm and badly bruised his cheek. He may have also have suffered a concussion.

Simon went to the hospital where he was treated and released the same day, sporting a bright yellow cast.

As we reported, this was not Simon's first crash ... in August, 2020, he got a brand-spankin' new e-bike and literally got on it in his driveway and it lunged forward, crashing and as a result, Simon broke his back in 3 places.

Now, if Simon happens to read this ... wear a helmet, dude!!! He wasn't wearing one in either crash, and but for the grace of God, he could have suffered way more severe injuries.

The 2022 Olympics haven't begun yet, but they're already off to a not-so-hot start for USA skier Kai Owens, who sustained a gnarly eye injury during preparation for the Beijing event on Tuesday.

The 17-year-old Owens was practicing for the Winter Olympics at Genting Snow Park in China ... when photographers captured her falling on the slopes.

Kai needed medical care from personnel on hand ... but, fortunately, she was able to stand up on her own. Photos from the scene, though, showed she did suffer a black eye in the fall.

Thankfully, it does not appear she sustained any further serious injuries.

It's not exactly the start Owens was hoping for ... remember, she told us out at LAX just a few days ago that she was pumped for the Games, particularly considering the location of it all.

Owens was abandoned by her birth parents in China as an infant and was adopted by a Colorado couple when she was 1 year old.

Lisa Venderpump got thrown for a loop on the horse she was riding ... and she ended up in the hospital with broken bones.

'The Real Housewives' star was riding her horse Sunday at The Paddock in the Los Feliz part of L.A., when the equine apparently got spooked, reared up and bucked her off. An eyewitness tells us she flew over the horse's head and landed squarely on her back.

Lisa was in a lot of pain, and for good reason ... we're told she broke her leg in 2 places, just above the ankle. She also has bruising on her back.

She was taken to the hospital by ambulance. Hubby Ken Todd followed behind and he's with her at the hospital now. We're told she'll undergo surgery. Our Vanderpump sources say once she's all healed, she'll be fine.

The horse is no stranger to Lisa ... they've been together for 6 years. Some friend!!!

Dr. Oz drew on his medical background for a medical emergency at a political meeting ... jumping in to help a man who fell unconscious.

Sources close to the situation tell TMZ ... Oz was next in line to speak at Saturday morning's Pennsylvania Republican Caucus Meeting outside Pittsburgh when suddenly a state committee member collapsed.

We're told Dr. Oz rushed over and quickly lowered the man to the ground ... tending to him while he appeared to suffer a seizure and lost consciousness.

Our sources say Oz also helped move the man to a flat surface outside the meeting room, where another seizure-like episode occurred.

We're told EMS eventually arrived and transported the man to a local hospital, and the guy was conscious and conversing with Oz as EMS took him away.

Our sources say Dr. Oz went on stage for his scheduled remarks after the incident ... and following the caucus, he got in touch with the man and learned he's in stable condition at a hospital.

As you know ... Dr. Oz is running for a U.S. Senate seat in Pennsylvania, switching gears to politics after a successful career as a TV doctor.

Dr. Oz tells TMZ ... "I am a doctor first and always will be, so I responded immediately to a call for help when a nearby man collapsed. Following the lessons learned from a life in medicine, I did my job until EMS arrived to transport him to a nearby hospital."

NHL star Nathan MacKinnon suffered both a broken face and a concussion from the violent hit that left him a bloody mess on Wednesday night.

Avalanche head coach Jared Bednar just announced the update to media members ... saying he's not sure when the Colorado center will be able to return to game action.

Bednar did say, though, that he expected MacKinnon to miss at least the team's next 3 games.

If you missed it ... the hit was scary as hell -- as MacKinnon was going up the ice in the Avs' game against the Bruins, Taylor Hall's shoulder collided with his face.

Video of the play shows MacKinnon's stick ended up wacking him in the nose ... 'causing him to bleed everywhere.

Somehow, MacKinnon got up and skated off the ice under his own power.

Colorado will miss the star while he's out ... he's been one of the best players in the league this season, tallying nine goals and 34 assists in 31 games.

Motorsports legend Travis Pastrana says he broke his back and hip in his horrifying parachute crash last weekend ... but somehow, he said he's expected to make a full recovery.

The X Games gold medalist and daredevil posted a video update from his hospital bed Thursday ... explaining his failed base jump attempt off a high-rise hotel in Ft. Lauderdale, Fla. last Saturday resulted in some serious injuries.

The 38-year-old said he broke the L5 vertebra in his back and suffered "multiple hip fractures" and a "pinned sacrum."

Fortunately, Travis said he's already up and moving around following the surgery ... adding, "Doctors say it's not going to be really any worse than what it is when I went in, which isn't saying much. Everything was fused down there anyway."

Pastrana went on to thank his sponsors, his fans and his family following the near-tragedy.

As we previously reported, Pastrana hit the ground hard after he appeared to deploy his parachute just a little too late after leaping off a building on Saturday morning.

He was rushed to the hospital in "serious but stable condition," authorities said.

Scary moment on the NHL ice on Wednesday ... Nathan MacKinnon -- one of the league's best players -- gushed blood everywhere following a violent hit, and had to leave his game early.

The gnarly scene all went down just minutes into the Avalanche's tilt with the Bruins in Denver ... when MacKinnon was trucked by Boston winger Taylor Hall as he tried to get after a puck.

Video shows Hall's shoulder went right into MacKinnon's face, and, unfortunately for the Avs star, his own stick caught him in the nose during the play as well.

The 26-year-old lay on the ice for several minutes ... bleeding all over the place, before he was eventually helped off by trainers into the locker room.

MacKinnon never returned to the game, and it's unclear the extent of his injuries. The Avs only said that he had an "upper-body" ailment.

Seems pretty clear from the images, though, that the guy might need to get his face fixed soon.

Scary moment at the Australian Open -- tennis star Nick Kyrgios smacked a loose ball out of frustration during a doubles match ... and it ended up nailing a young fan in the crowd.

Fortunately, the kid appeared to be OK after Kyrgios apologized with a gift racket.

The wild play all went down Monday during Kyrgios' doubles event with partner Thanasi Kokkinakis ... when Kyrgios got pissed over a missed serve.

You can see in footage from the Open, Kyrgios rifled a ball into the ground, and it ended up ricocheting straight into the stands and right into a kid's stomach.

The boy was so visibly hurt and upset ... Kyrgios himself was shaken up on the court.

Nick, though, collected himself and immediately grabbed one of his spare rackets to make up for the major blunder. And, it seemed the child was going to be just fine after the present.

"I saw it heading towards the kid and I thought, "Oh, no, I am getting defaulted," Kyrgios said of the scene to Channel Nine after the match. "I was glad he was OK and I gave him the racket."

This isn't the first time Kyrgios has made headlines at this month's tourney -- just last week, the 26-year-old took a swig of a fan's beer after defeating his opponent.

The fans in attendance loved it ... but the gesture didn't come without controversy, as some wondered if event organizers would come down hard on the Aussie ... given the COVID drama that went down with Novak Djokovic in the buildup to the tourney.

But, Nick has yet to face any discipline for the not-so-safe action.

One of the people involved in Arnold Schwarzenegger's multi-car wreck couldn't believe her eyes ... not only because of the movie stunt-like crash, but because she's a huge fan of his.

Habiba Muminova was one of the drivers who had a close encounter with Arnold's SUV in Friday's crash, and she tells TMZ ... she felt like she was "hallucinating" when Arnold exited his Yukon.

Habiba says Arnold's one of her favorite actors, and while she says, "God bless him," ... she's painfully aware this wasn't exactly a great way to meet him for the first time. Still, she says she's telling everyone what -- and who -- happened.

Habiba says she was just doing her job Friday -- driving patients to doctor's appointments -- when all of a sudden she was smack in the middle of an accident involving a movie star/former governor.

She says she was waiting at a red light to turn on Sunset Blvd when Arnold's SUV collided with a red Prius ... and before she knew it one of Arnold's back tires was smacking into her car, causing a harsh jolt.

Habiba says the initial impact was so strong, she thought she broke her spine.

With Arnold's SUV blocking her door, Habiba says she climbed out through the passenger side, where she was met by first responders and advised to get a ride to the hospital. Instead, she stayed put on the scene with the patient she'd been transporting.

She says she's now experiencing pain in her spine and back, from the shoulder down her left side and she's getting checked out by a doctor this week.

Habiba's concerned about her job moving forward -- she says her car is badly damaged, which will make it difficult, if not impossible, to drive patients around town.

She says she's reached out to an attorney for legal advice.

Motorsports legend Travis Pastrana has been hospitalized in Florida ... after he terrifyingly crash-landed into a park following a parachute stunt gone wrong.

The horrifying scene was all captured on video ... showing Pastrana is truly fortunate to be alive today.

In the footage, you can see the 38-year-old jumped from the top of a high-rise hotel ... and appeared to deploy his 'chute just a little too late, causing him to hit the ground with force.

Thankfully, his publicist told WSVN-TV's Frank Guzman he is expected to make a full recovery.

"Surgery went well and he is excited to get home and heal up," the publicist said.

Ft. Lauderdale Fire Chief Stephen Gollan tells TMZ Sports the incident happened on Saturday morning, when a video crew was shooting in the area of Las Olas Blvd. and Andrews Ave.

"A stunt during that event did not go as planned resulting in a hard landing of a parachutist that jumped from the Hyatt Hotel," Gollan said in a statement.

"The adult male was immediately treated and transported in serious but stable condition to Broward Health."

According to Keys Weekly, the X Games gold medalist has been in Florida this month doing stunts and drifts. In fact, just a few days before the parachute incident, Pastrana was in the Florida Keys filming with a 1983 Subaru GL Wagon.

Scary moment for Olympic gold medalist Sofia Goggia ... the alpine skier banged her head and busted her leg during a violent crash at the World Cup on Sunday -- just weeks before she's supposed to defend her title at the winter games in Beijing.

Luckily for Goggia, the injuries aren't catastrophic.

The frightening incident was caught on video ... showing the 29-year-old going full speed downhill at the Cortina d'Ampezzo Super-G event.

Everything appeared normal until the Italian skier lost control on a turn ... sending Goggia flying through the air.

Goggia -- who was wearing a helmet -- eventually landed and slid headfirst down the mountain before finally coming to a complete stop.

It looked very bad ... but thankfully, the Italian Ski Federation announced she suffered a left knee strain, a partial tear in her cruciate ligament and a small fibula fracture.

Goggia's rehabilitation will start on Monday as she's determined to defend her downhill gold medal title at the 2022 Winter Olympics in Beijing ... which happens on Feb. 15.

"It's a shame that this injury comes in a very important moment of the season," Goggia said, "but in the next few hours I'll start the physio treatment so I can try to defend my title in the discipline I love the most."

Conor McGregor's return to the Octagon likely isn't that far away ... according to UFC President Dana White, who tells TMZ Sports he expects the Irish superstar to fight this summer.

We recently asked White ... do you believe Conor will fight this year after healing up from the devastating injury.

"I think so, yeah," Dana told us. "He's doing all the right things with his leg. I'm hoping he can come back this summer."

Of course, 33-year-old McGregor hasn't stepped foot competitively in the cage since snapping his leg against Dustin Poirier in July 2021.

Injury aside, The Notorious -- a former UFC double champion -- has lost 3 of his last 4 fights ... including the last 2 to The Diamond.

Conor is currently ranked 9th in the UFC's Lightweight division ... behind fighters like champ Charles Oliveira, Justin Gaethje, Poirier, Michael Chandler, and Tony Ferguson, to name a few.

We also talked to the UFC honcho about the barn-burner of a scrap between Calvin Kattar and Giga Chikadze ... a fight the #5 ranked striker from Boston won by unanimous decision.

So, what's next for Kattar? Dana doesn't know just yet, but makes it clear Calvin is in a prime position.
