Nurse!

A man working at CBS' famous TV and film studio was injured when part of a 600-lb. wall collapsed on him ... TMZ has learned.

Our sources say the workplace accident went down June 7 at the CBS Radford lot in Studio City around 8 in the morning. The L.A. Fire Department and paramedics were called to the scene.

We're told the emergency staff treated a man who was injured when a portion of the enormous wall on a sound stage fell on him.

According to Cal/OSHA ... the worker, listed as an employee of CBS Studio Center, was hospitalized for a dislocated shoulder, and an investigation into what happened is underway.

It's unclear if he was working on a specific production at the time of the accident. A CBS source says it was not one of their own shows. The location is known as the home to several popular shows -- for instance, "Big Brother" and "The Conners" -- but not all of them air on CBS.

Kelsey Salmon is fending off a different kind of attack -- chihuahua lovers are accusing her of dragging the breed through the mud over her eyelid-biting incident.

Kelsey tells TMZ ... she's been flooded with tons of social media hate from the chihuahua community ... claiming she conjured up this whole episode just so people would turn on the tiny breed.

The victim shaming is pretty obvious just from looking at Kelsey, and her reattached eyelid, for Pete's sake!!! Yet, she still wants to make it clear, she's in no way saying all chihuahuas are violent.

Remember, Kelsey told us she loves dogs -- owns pooches of her own -- and she didn't even say the eyelid tech's dog that chomped on her should be put down.

Still, she says the messages have been vicious. One person wrote, "You only saying Chihuahua instead of Chihuahua Mix [because] a lot of hate going towards the bred, which already gets hate because of bad owners. Maybe instead of hating the dog, you should hate its owner for raising it like that."

Kelsey says it's all ratcheting up her anxiety ... even as she's in danger of losing the reattached eyelid. She described what doctors will do if that happens, and it ain't pretty.

BTW, Kelsey tells us she still hasn't heard from the lash tech. As for a lawsuit ... the family's contacted their lawyer but still, no decision has been made whether to move forward.

Danish soccer star Christian Eriksen is getting a "heart starter" implanted to his chest soon ... a big step toward ensuring he never suffers another terrifying cardiac episode again.

Denmark national team doctor Morten Boesen made the announcement Thursday ... saying after multiple exams on the athlete, specialists have determined the 29-year-old needs an implantable cardioverter-defibrillator.

"This device is necessary after a cardiac attack due to rhythm disturbances," Boesen said.

"Christian has accepted the solution and the plan has moreover been confirmed by specialists nationally and internationally who all recommend the same treatment."

As we previously reported, Eriksen went into cardiac arrest during last Saturday's Denmark vs. Finland game in Copenhagen ... and the scene was horrifying.

Eriksen collapsed on the pitch and needed a defibrillator to be revived ... and he's been in the hospital ever since.

Eriksen, though, has been in good spirits while recovering -- the soccer player posted an update from his hospital bed earlier this week saying, "I'm fine -- under the circumstances."

It's unclear if Eriksen will be able to play soccer again ... but he did make it clear he'll certainly be cheering on the Denmark team as it takes on Belgium on Thursday.

Jessie J's condition with Ménière’s disease has been compounded exponentially ... now she's also suffering from major acid reflux that's causing nodules in her throat.

The singer revealed the new medical drama while explaining why she posted video of herself quietly singing her new single, "I Want Love." Jessie, who choked back tears during the  video, said her speech therapist asked her to record herself singing quietly so they could hear her voice and mark any progress.

Problem is ... Jessie said back in February she started feeling a constant burn in her throat. She said she ignored it and presumed it was fatigue from the studio -- but a doctor eventually told her she has major acid reflux and nodules in her throat.

She said the acid reflux was presumably caused, at least partially, by steroids she had taken to treat her Ménière’s disease, but the root cause is still not clear.

Jessie immediately went on anti-acids and a 2-week run of no talking -- but she says it didn't stop the nodules from forming. It's been an incredible ordeal ... she says 6 different doctors have had 8 cameras down her nose, had to adjust her diet to eat the same 6 foods for 3 months, plus blood work, acupuncture and massages.

All of that seemed to work because the nodules went away ... but she says doctors have told her if she continues singing, they'll come right back.

Jessie's trying to fight through it, though, saying, “I am doing all I can to mend whatever it is that is broken to be able to sing these songs live. I will not mime. I refuse."

Tampa Bay Rays prospect Tyler Zombro is clearly lucky to be alive today ... the pitcher revealed he needed brain surgery after being drilled in the head by a line drive this month -- and the scar he showed off Thursday is gnarly.

Zombro -- who was struck by a comebacker in a minor league game on June 3 -- posted pics from his recovery on his Twitter page ... and it's truly miraculous he appears to be okay following the scary scene.

Zombro showed the entire right side of his head was opened up by docs after he was hit by the baseball ... and then later closed up with a grip of staples.

"Unbelievably grateful to be in the situation I’m currently in with the incredible help from @DukeHospital & staff," Zombro said.

"To all of you that have showered my family and I with positive thoughts, I have no doubt that all of the prayer support kept God with me throughout that night, as I’m in a very fortunate position all things considered."

The initial injury was one of the scariest incidents anybody's EVER seen on a baseball diamond ... Zombro let a fastball go and it was smacked right back at him.

The 26-year-old could be seen convulsing on the mound and was immediately rushed to the hospital.

In fact, things looked so dire, Zombro's minor league team, the Durham Bulls, postponed their game the following day in wake of the injury.

But, Zombro said Thursday he's doing much better ... even cracking a joke about his sprint speed!

"In optimistic news: I’ve never been the fastest on the field so I may have gotten a boost after this surgery," Zombro said.

Zombro added he intends to get back on the diamond eventually ... though there's no timetable for a return at this point.

LeBron James says the rash of injuries in this year's playoffs are all the NBA's fault ... claiming the bumps, bruises, tears and sprains are entirely due to the league's early start date.

Bron went off on the league in an epic Twitter rant Wednesday ... claiming he saw this coming from a million miles away once the NBA decided to start its 2021 season in December despite finishing the 2020 season in October.

"They all didn’t wanna listen to me about the start of the season," said LeBron, who did insist back before the season began that a December date was way too early to come back.

"I knew exactly what would happen. I only wanted to protect the well being of the players which ultimately is the PRODUCT & BENEFIT of OUR GAME!"

The NBA playoffs have been marred by injuries so far ... mega stars like Anthony Davis, Joel Embiid, James Harden and Kyrie Irving have all missed time.

And, on Wednesday, it was announced Clippers star Kawhi Leonard could be done for the playoffs with a knee injury as well.

All of it has Bron fuming ... claiming it could have all been easily prevented.

"This is the best time of the year for our league and fans but missing a ton of our fav players. It’s insane," LeBron said.

"If there’s one person that know about the body and how it works all year round it’s ME! I speak for the health of all our players and I hate to see this many injuries this time of the year. Sorry fans wish you guys were seeing all your fav guys right now."

LeBron added, "And I know all about the business side too/factors so don’t even try me! I get it."

Awesome update from ex-NFL star Greg Olsen -- his son, TJ, just "rang the bell" to symbolize the end of treatment after receiving a heart transplant!!!

Olsen shared footage of the special moment at the hospital in Charlotte on Wednesday, saying, "Today we 'rang the bell,' and for the first time our family whole again."

"To everyone who prayed for our little buddy and sent us words of encouragement and support ... All we can say is THANK YOU and WE 💚 YOU ALL"

As we previously reported, TJ was born with a congenital heart disease that required 3 open-heart surgeries before his 3rd birthday.

Olsen revealed late last month TJ's heart was failing ... and doctors said he would need a transplant immediately.

TJ was quickly able to find a match and underwent surgery earlier this month ... and despite all the struggles, Greg says his son remained optimistic throughout the journey.

"TJ’s positive attitude and selflessness throughout has been an inspiration to us all," he added. "Never did he feel sorry for him self or play the victim. All he did was talk about what the future held and the things he looked forward to doing."

"It's not as bad as it looked."

That's UFC fighter Jamahal Hill telling TMZ Sports the nasty injury he suffered during UFC 263 on Saturday is gonna be FINE ... and he's already thinking about his next fight!!!

YO, THAT'S CRAZY CONSIDERING IT LOOKED LIKE HILL'S ARM WAS SNAPPED IN TWO!!

The backstory ... Hill was fighting Paul Craig when the 30-year-old got caught in an armbar and Paul pulled Jamahal's left arm in a way it's not supposed to bend!

The good news ... Hill confirms the arm was NOT broken -- "just dislocated pretty badly."

"They were able to pop it back in and the doctor said it’s rock solid. It’s doing all the movement that it needs to, it’s just going to be sore for a while."

So, what's next?

"I’ll follow up with my doctor when I land back at home and we’re going to go from there. Hopefully I can be back in real soon."

As for the pain, Hill says there was a "little discomfort" -- but that's it!

He was more upset about getting caught in the armbar in the first place and losing the fight.

But, Hill's a tough guy and vows to return to the Octagon ASAP -- and he even wants to run it back with Craig!!

"I gotta handle whatever I gotta handle through the loss or whatever, that I just went through. But, definitely I hope he keeps winning, so that way next time we meet is for some serious marbles. But yeah, that’s definitely one I want to run back."

There's more ... Hill also talks about his future and addresses the criticism of the referee who was working the fight.

But, Hill also delivered this message to his fans ...

"I just want everybody know I’m good, I’m alright. I’ll be back."

Just days after he collapsed on the soccer field, Christian Eriksen is speaking out -- vowing to fight in his recovery while doctors continue to hunt for the cause of the medical emergency.

"'Thank you, I won't give up," Eriksen said in a statement issued through his agent to the Italian media outlet, Gazzetta dello Sport.

"I feel better now -- but I want to understand what's happened."

The statement continued, "I want to say thank you all for what you did for me."

As we previously reported, the 29-year-old went into cardiac arrest during Saturday's Denmark vs. Finland game in Copenhagen.

Emergency medial personnel raced onto the field to treat him -- and he was eventually resuscitated with a defibrillator.

Eriksen was transported to a nearby hospital where he continues his recovery. He's currently in stable condition.

The Denmark team doctor, Morten Boesen, spoke with the media on Sunday and addressed the seriousness of Eriksen's situation in the seconds after the soccer star collapsed.

"He was gone," Boesen said ... "And we did cardiac resuscitation. And it was cardiac arrest."

He added, "How close were we? I don’t know. We got him back after one defib. That’s quite fast."

As for what caused the incident, Boesen said specialists are still trying to figure that out.

"I’m not [a] cardiologist, so the details about why it happened and further, I will leave to the experts."

Bottom line ... Eriksen seems to be on the road to recovery, which is a miracle considering how scary things looked on Saturday.

Christian Eriksen -- a Danish soccer player, who's one of the stars on the national team -- just had a frightening emergency during the first round of the UEFA European Championship ... collapsing on the field and requiring immediate medical attention.

The 29-year-old midfielder fell to the ground Saturday during Denmark's Euro 2020 match against Finland, toward the end of the first half. He was jogging back and about to receive a ball being thrown to him from one of his teammates, when all of a sudden ... Eriksen toppled over without provocation -- not being touched by another player or anything.

Everyone around him instantly recognized he was suffering an emergency and called for the ref to stop the game -- while also waving on team doctors and other first-responders on hand. Footage was captured from the terrifying moment ... and it's clear he'd lost consciousness.

Reports say CPR was rendered to Eriksen on the spot before he was carried off a stretcher for further treatment. His team -- including players from the other side -- were notably concerned, with a majority of them taking a knee out of respect ... a tradition in soccer.

His teammates also linked arms around Ericksen and formed a wall of sorts -- seemingly to give him privacy while he was being tended to. No word yet on his status or what might've caused the collapse. Of course, everyone is sending their thoughts and prayers.

Kelsey Salmon's trip to get her eyelashes done ended in the worst possible way ... with a little dog attacking her and biting off the finished product, along with her entire left eyelid!!!

The photos are brutal -- that's a warning for the queasy -- but not as brutal as the experience the 23-year-old from Atlanta has been through since going to a lab technician she found on Instagram.

According to Kelsey ... her normal lash lady was booked, so she went to a lash tech who worked out of her home ... and had a pet chihuahua.

Kelsey says the dog jumped up on her lash bed while she was getting her lashes done, she was petting it ... and everything was fine. But, when she was done, she says she sat up and the dog was on the floor looking up at her.

"Then, out of nowhere -- it happened so fast that I didn't have time to pull back -- he jumped up, bit me in the face and broke my eyelid off."

What Kelsey describes next is a horrific scene of blood and chaos as the ambulance was called, and she was rushed to the ER. After hours of waiting, she says she had to go to another hospital for surgery ... and miraculously, they were able to successfully reattach it.

To make this all worse, Kelsey was getting her lashes done for a birthday trip to Hawaii when this all went down. Fortunately, she still got to go, but with her left eye completely sewn shut ... and she says the doctors told her it could take up to a year to fully heal.

Jockey Irad Ortiz Jr. was thrown off his horse and kicked in the head by another during a race Thursday ... but somehow, the dude miraculously avoided serious injuries.

The rider's agent, Steve Rushing, announced the good news on Friday ... saying that despite the horrifying fall, Ortiz Jr. will only need to miss a couple weeks from his job.

"He said he felt better today, than he did last night," Rushing told Daily Racing Form. "I told him I don’t know what brand of helmet you have, but make sure you get another one."

Rushing added Ortiz Jr. needed 6 stitches in his head and 5 in his arm ... but is expected to make a full recovery in a matter of days.

It's all quite frankly incredible, given just how gnarly the accident was.

Footage from the track showed as Ortiz Jr. was coming down the stretch ... his horse stumbled and bucked the rider to the ground.

When Ortiz Jr. hit the dirt, he was then kicked in the head by a trailing horse ... and ultimately needed to be stretchered off the track.

Ortiz Jr. was set to ride Known Agenda in Saturday's Belmont Stakes ... but he'll miss the event now. A replacement rider has not yet been named.

Canadiens player Jake Evans was forced to leave the ice on a stretcher Wednesday after a violent hit ... and his teammates are now calling the play both "dirty" and "disgusting."

The incident all went down late in the third period of Game 1 of Montreal's playoff series with Winnipeg ... when Evans scored a wraparound, empty-net goal.

Immediately after the puck crossed the red line, though, he was demolished by Jets player Mark Scheifele ... and Evans hit the ice HARD.

You can see in footage of the play, Evans landed face first ... and laid motionless on the ice while Canadiens players raced in to defend him.

While Montreal coach Dominique Ducharme said Evans did NOT need a trip to the hospital, Ducharme did say Evans still needed to undergo further evaluation after the Canadians' 5-3 win.

And, Evans' teammates were NOT happy about any of it ... even though Scheifele was hit with a penalty and ejected.

Forward Jesperi Kotkaniemi told reporters after the game the hit was "disgusting" ... while defenseman Joel Edmundson called it a "dirty" move.

"If he gets back in the series," Edmundson said of Scheifele, "we're going to make his life miserable."

Jeff Lewis has nothing to flip out about following cosmetic surgery to his eyelids ... because he seems to be having a blast documenting his totally chill recovery.

The "Flipping Out" star shared a couple of, umm ... unique looks over the holiday weekend as he's recuperating from the procedure to his lower eyelids.

The first one where he's resting on the couch with frozen peas on his eyes as his daughter tends to him. Jeff captioned the photo, "Recovery is going well."

Then on Monday, Jeff posted a "Day 3 of Recovery" pic of himself lounging on his patio with most of his face still wrapped in gauze ... but wearing shades. He paired it with Sheryl Crow's "Soak Up the Sun."

Last week on his SiriusXM radio show, Lewis explained that the "fat repositioning" eyelid surgery should make him look more youthful and rested.

He said, "This is kind of a cutting-edge procedure. Normally, they'll suck out the fat, but this doesn't require folding of the skin or stitching or pulling. They go inside my eye lid but it doesn't change the shape of your eye."

All that being said, Jeff added ... "It's not like a huge, big difference."

Incredible scene during Maple Leafs' workouts Thursday ... John Tavares was back on the ice just 1 week after severely injuring his head -- and he looked GOOD!!!

Tavares took a flying knee to the face last Thursday ... and the damage was so bad, the 30-year-old Toronto captain had to spend the night in the hospital.

But, great news, Tavares is already back on the ice ... reporters shot video of the dude skating around the Toronto rink Thursday morning as if nothing had happened!!

Check out the clip, Tavares appeared to be moving just fine ... ripping slap shots and weaving around the ice no problem.

According to TSN's Kristen Shilton, Tavares' on-ice work lasted about 20 minutes ... before he eventually headed back into the locker room.

It's unclear if this means a return to actual gameplay is nearing for Tavares ... last week, the Leafs said in a statement John would be out "indefinitely."

WARNING: LOOK AWAY IF YOU'RE SQUEAMISH!!!

Atlanta Braves star Marcell Ozuna JACKED UP his hand sliding into a base during a game Tuesday night ... and there's worry he could now miss significant time over it all.

The gnarly injury all went down in the 3rd inning of the Braves game against the Boston Red Sox at Fenway Park ... when Ozuna was trying to avoid a tag at third base.

In video of the play, you can see as the ATL outfielder went head-first into the bag ... his hand got caught on Red Sox star Rafael Devers' left foot.

Ozuna's fingers were crunched so badly at impact, TWO of them dislocated -- and the digits were apparently so wonky after the collision, players on the field had to look away!

Braves manager Brian Snitker said after the game the ring finger AND the middle finger on Ozuna's left hand were popped out of place ... and he's being sent back to Atlanta for further evaluation.

"I saw him," Snitker said. "He had splints on [the fingers]. He wasn't feeling real bad, but it did them both. So, they're just going to make sure everything's good in there."

Snitker continued, "Hopefully it's just, you know, put them back [in place] and he's a little stiff for a few days."

Ice up, Marcell ... and get better soon!
