Nurse!

Chris Kattan is hospitalized after a scary health situation forced him into emergency surgery ... and as a result, he'll miss some upcoming dates in his comedy tour.

Sources connected to Chris tell TMZ he recently came down with Streptococcus Pneumoniae, an extreme case of pneumonia, and on Sunday was rushed to the hospital. From there, he needed emergency surgery, but thankfully the operation was successful.

We're told as long as things continue to go well, Chris will be released from the hospital Friday, and can hopefully return to work sometime in the near future.

Unfortunately, Chris had a show lined up for this Friday in Valparaiso, IN ... which we're told will have to be rescheduled, along with some other upcoming tour dates.

As you know, Chris stayed out of the limelight for a while, but is back to doing standup.

Of course, he had an 8-year run on "SNL" where he was featured in some iconic sketches, playing Mango or boppin' his head with Will Ferrell during "A Night at the Roxbury."

BTW -- we got Chris at LAX earlier this year telling us how he was champing at the bit to revive the 1990s cult classic comedy -- he said he'd wanted a "Roxbury" sequel for years, and had ideas about how to bring it into the 21st century.

Dustin Poirier was just released from the hospital after battling a nasty Staph infection -- but the UFC star refused to miss even a beat of daddy duty -- the lightweight contender went straight to watch his daughter in her school play!

33-year-old Dustin, on crutches, along with his wife, Jolie, attended their six-year-old daughter Parker's play in Louisiana ... where his adorable little girl was dressed as an angel.

"Straight from the hospital to the school play to see my little angel this morning!" Poirier wrote on social media.

Just a day ago, Poirier was laying in a hospital bed as doctors treated his left foot ... after he came down with a Staph infection.

According to the Mayo Clinic, "Staph infections are caused by staphylococcus bacteria." They typically clear up after the patients been treated with an antibiotic. But, MC says that's not always the case.

"However, some staph infections no longer respond, or become resistant, to common antibiotics. To treat antibiotic-resistant staph infections, health care providers may need to use antibiotics that can cause more side effects."

Dustin posted a photo of the mangled appendage ... and captioned it with what we were all thinking -- "Wut da helllll?"

As serious as the infection can be, it's great news to see DP discharged from the hospital.

Poirier was last in the Octagon at UFC 281 ... where he defeated Michael Chandler in one of the year's most exciting fights.

It's unclear how long it'll be until Dustin's ready to fight again.

Take a deep breath, Bills Mafia -- Von Miller says everything is going to be okay after undergoing season-ending ACL surgery ... sending a heartfelt message to his fans from the hospital bed.

Miller posted a video shortly after the bad news broke ... saying, "Yerrr! Bills Mafia, what's good? I'm good man. I'ma be right back, man."

"Mentally, I couldn't be in a better spot and I think that is the majority of it. Don't feel sorry for me, don't say I hate it for you -- none of that stuff 'cause I am good!"

The Bills announced on Wednesday that the star pass rusher -- who signed a 6-year, $120 million contract this offseason -- is sidelined for the rest of the season due to the injury ... but Miller is already looking forward to getting back to 100%.

"I'm excited for the opportunity to show my teammates how tough I am, how hard I work, and how important that this means to me. I love you guys, and I appreciate you guys. All love and respect. Don't blink, baby!"

Miller suffered the injury against the Detroit Lions at Ford Field on Thanksgiving Day ... but the initial belief was that the 33-year-old avoided significant knee injury.

According to head coach Sean McDermott, Von checked in to the hospital for exploratory surgery ... but doctors told the two-time Super Bowl Champ that he tore his ACL instead.

McDermott called the injury a "very unfortunate situation" for Miller and their team ... adding he knows how much #40 will miss being out there with the guys.

A man has been arrested in connection to the brutal baseball bat attack in NYC last week -- and cops say it appears to be totally random ... because the suspect and victim were total strangers.

36-year-old Karim Azizi was hauled in by the NYPD Wednesday morning on three different charges -- assault, attempted assault and criminal possession of a weapon. Of course, Azizi is the man cops suspect was behind the brutal attack that was captured on camera.

Law enforcement sources tell us the perp and victim were total strangers, and that the beating seems to have come out of nowhere, despite some believing it may have been targeted at first. A warrant squad, we're told, picked Azizi up at his Hamilton Heights home.

Our sources also say ... the video of the incident assisted in capturing him.

As we reported ... the victim was walking on the sidewalk minding their own business, when suddenly -- the attacker pulls a bat out and hits the victim in the back of the head.

Sen. Ted Cruz says his teenage daughter is "okay" after cops were called to his Texas home Tuesday night for a medical emergency.

Houston PD responded to Cruz's house in Houston's River Oaks neighborhood around 8 PM after receiving a report of a 14-year-old with self-inflicted stab wounds to their arm. The Senator, his wife Heidi and their 2 daughters, ages 11 and 14, live in the house.

One person was rushed to a hospital for treatment. Although police are not disclosing the patient's name, Cruz's rep issued a statement to ABC News, saying ... "This is a family matter and thankfully their daughter is okay."

It's unclear if Sen. Cruz was home at the time, or who called 911.

His rep adds, "There were no serious injuries. The family requests the media respect their daughter's privacy at this time."

UFC star Dustin Poirier provided an update on his battle with a gnarly Staph infection on Tuesday ... showing off his swollen left foot from his hospital bed.

"The Diamond" has been getting treatment all week ... and judging by his recent pic, it ain't goin' too hot for the lightweight.

"Wut da helllll," Poirier said on Twitter ... alongside a shot of the deformed foot.

Poirier is hoping to finally get out of the hospital on Wednesday ... but made the best of his stay on Monday night, when he tuned in to his New Orleans Saints' matchup against the Tampa Bay Buccaneers.

Unfortunately for Poirier, it wasn't too fun of an experience -- his home team ended up losing in the final seconds as Tom Brady and Co. pulled off the wild comeback.

Poirier -- who beat Michael Chandler in November -- also took advantage of his time by talking trash with Conor McGregor ... saying he's down to step in the Octagon with him for a fourth time.

Terrifying scene ahead of the Atlanta Hawks game on Monday night ... Bob Rathbun, the team's play-by-play announcer, suffered a frightening medical emergency while on air -- and needed to be rushed to the hospital.

Thankfully, however, the 68-year-old is now said to be doing better ... and is in "stable" condition.

Rathbun was previewing the Hawks' game against the Thunder for Bally Sports with Dominique Wilkins ... when he suddenly appeared to lose consciousness in his chair, and convulse uncontrollably.

WARNING -- THE VIDEO IS HARD TO WATCH.

Medical personnel raced to his side to tend to him before the cameras cut away.

According to Bally Sports officials, he was suffering from dehydration ... and was taken to a local medical facility. They added he's now both "stable" and "responsive."

Lauren Jbara filled in last-minute for Rathbun to call the game -- which the Hawks lost, 121-114.

Get well soon, Bob.

WWE Hall of Famer Barry Windham, the maternal uncle of WWE star Bray Wyatt and former WWE wrestler Bo Dallas, suffered a heart attack over the weekend and is now in the ICU.

According to a GoFund Me campaign created by Barry's niece, Mika Rotunda, the 62-year-old went into cardiac arrest while traveling through an airport in Atlanta.

Mika says her uncle underwent an emergency procedure to save his life ... adding the wrestling legend's future is uncertain.

Windham, son of Robert Deroy Windham, better known by his ring name Blackjack Mulligan, was a household name in National Wrestling Alliance and WCW.

One of the most memorable moments of Barry's career was when the 4-time NWA/WCW tag team champion turned heel on Lex Luger and joined the Four Horsemen.

The Four Horsemen was a wrestling group originally in NWA and later WCW ... that consisted of Ric Flair, Arn Anderson, Ole Anderson, and Tully Blanchard.

Windham was inducted into WWE's Hall of Fame in 2012 alongside Flair, J.J. Dillon, Arn Anderson, and Blanchard.

Nick Cannon just had a major health SCARE ... landing him in the hospital with pneumonia.

The "Masked Singer" host posted a photo of himself in a hospital bed, wearing a face mask, gown and beanie.

The father who has welcomed 11 kids with 2 on the way casually revealed his diagnosis to his millions of IG fans ... "It's just pneumonia, nothing I can't handle. Okay, so I guess I'm not Superman."

Then Nick became more serious, making a veiled reference to his 10-year battle with the autoimmune disease lupus ... "I promised myself I would never be back at this place again… great lesson to take care of YOU or YOU won't be able to take care of everyone else."

Nick said he didn't want prayers or well wishes...he just needs some much-needed rest and he'll be back "stronger than ever."

What's more ... Nick is currently on his "Cannon Wild 'N Out" tour and performed a sold-out show Thursday night at Madison Square Garden in NYC. He reflected, "Now I'm all alone in a tiny hospital room. Life is definitely a rollercoaster!"

Aerosmith called off their concert Friday night in Las Vegas ... this after Steven Tyler had fallen ill.

The legendary rock band was set to perform at Dolby Live at Park MGM as part of their "Deuces Are Wild" residency ... but Steven got sick about 2 hours before they were to hit the stage. It's unclear what the medical issue was that benched the band.

The group posted a statement to Instagram ... "It is with great disappointment that we are forced to cancel tonight's show in Las Vegas due to Steven feeling unwell and unable to perform. He is expected to make a full recovery for Monday night's Las Vegas show. We sincerely apologize for the last-minute notice." All tickets will be refunded.

Back in May, the singer also experienced health problems ... Steven voluntarily went to rehab after relapsing on pain meds following foot surgery.  As a result, Aerosmith was forced to cancel the first leg of their Vegas residency over the summer. They started performing again in September.

The United States just got some GREAT news ahead of Saturday's match against the Netherlands -- Christian Pulisic has been cleared to play after suffering an injury against Iran.

Captain America's been recovering from getting hit in the balls a pelvic contusion this week ... which came after making contact with Iran's goalkeeper after scoring the game-winning goal.

CP said Thursday he was taking it one day at a time ... but was doing "everything in my power" to make it out on the pitch on Saturday.

Pulisic also clarified his injury was, in fact, a pelvic contusion ... saying, "I didn't get hit in the balls."

"I'm alright. It was very painful. That bone is there for a reason to protect you and I hit it well. I was sore."

He posted a Snapchat from his hospital bed after the 1-0 win on Tuesday ... promising he'd be back for their next match -- but admitted the pain was pretty tough to fight through.

The 24-year-old is holding up on his promise ... 'cause Pulisic is now good enough to go as the Red, White and Blue head into the round of 16.

U.S. soccer superstar Christian Pulisic wants everyone to know his gonads are perfectly intact ... telling reporters his World Cup injury was legitimately a "pelvic contusion" -- and not a made-up term for sore testicles.

Pulisic was injured after colliding with Iran's goalkeeper during his game-winning goal for Team USA on Tuesday ... forcing him to miss the second half of the match.

The 24-year-old midfielder was hospitalized after the contest ... but updated his supporters with a selfie, saying he'd be ready to take the pitch on Saturday against the Netherlands.

Based on the area of contact during the incident, many believed Christian's "pelvic contusion" diagnosis was just a code word for getting hit in the family jewels ... but now, all that speculation can be put to rest.

"I didn't get hit in the balls," Christian said with a laugh. "I'm alright. It was very painful. That bone is there for a reason to protect you and I hit it well. I was sore."

Christian says he's still taking it one day at a time ... but is doing "everything in my power" to be back in time for Saturday's match.

Terry Bradshaw's family show, "The Bradshaw Bunch," won't be returning for a 3rd season, TMZ has learned, and the reason has to do with Terry's health.

Production sources tell TMZ ... the E! show was renewed for a third season and filming was supposed to begin last March, but around that time Terry informed producers he had a serious health condition, which demanded his full attention.

At the time, we're told Terry didn't give specifics on his diagnosis but he let producers know he couldn't move forward with the show. In the end, our sources say the Bradshaws and E! mutually decided to not go forward with the series. The network has never disclosed the show was canceled.

Last month, Terry revealed on NFL on FOX he went in for an MRI for what he thought were neck issues ... and that's when doctors discovered a tumor and diagnosed him with Merkel cell carcinoma -- a rare, aggressive form of skin cancer.

Terry had been diagnosed with bladder cancer in November 2021, during the airing of the second season of the show.

The series, which was filmed at the family's ranch in Oklahoma, was centered around the 4-time Super Bowl champ, his wife Tammy and their 3 daughters.

Pittsburgh Penguins defenseman Kris Letang -- one of the biggest stars in the NHL -- has suffered a stroke ... and will now be off the ice indefinitely, his team announced Wednesday.

General manager Ron Hextall said Letang was diagnosed with the stroke on Monday after suffering symptoms. The GM called the news "shocking" -- but added the 35-year-old is currently in good spirits.

"We are grateful that Kris is doing well," Hextall said. "We are thankful to the medical staff and the physicians at UPMC."

Letang -- who previously suffered a stroke in 2014 and missed over two months of that season -- has now been ruled out of Penguins games for the foreseeable future.

"He is a warrior on the ice," Hextall added, "but first and foremost, he is a son, father, husband and friend. His health is our number one priority."

Added Letang, "I am fortunate to know my body well enough to recognize when something isn't right."

"While it is difficult to navigate this issue publicly, I am hopeful it can raise awareness. It is important for me that my teammates, family and the fans know that I am okay. I am optimistic that I will be back on the ice soon."

Letang has played in 21 games this season, logging one goal and 11 assists.

A parachute likely saved a base jumper's life, but not the way you think ... the chute got stuck on a rock moments after the man slammed into a cliff wall, preventing him from careening to the ground at high speeds from 100 feet above.

It all happened over Thanksgiving weekend at the Kane Creek Canyon in Moab, Utah ... about 4 hours southeast of Salt Lake City.

Hikers at the location recorded a base jumper leaping off a 400-foot cliff known as the Tombstone ... when out of nowhere, a gust of wind seized the parachute, forcing him right into a rock wall at a high rate of speed, seemingly knocking him unconscious.

What happened next probably saved the jumper's life ... the chute got caught on the cliff and stopped him from falling to the ground with, at best, a partially deployed chute.

The jumper was rescued after hanging on to the chute and the cliff for over an hour, according to FOX 6 ... and was airlifted away.

Of course, base jumping is the sport of jumping off of fixed objects like buildings, bridges and in this case, cliffs. Yes, it's very dangerous ... jumping from relatively low heights, and near objects, the chance for serious injury or death is very real.

Brazilian soccer legend Pele has been hospitalized again ... but his daughter is assuring the public there is "no emergency" regarding her father's health.

The 82-year-old has been battling colon cancer, and has been in and out of the hospital on multiple occasions since his diagnosis in 2021. But, following his latest visit to a Sao Paolo medical facility this week, ESPN Brasil reported the famed soccer player's health was "worsening."

Pele's daughter, however, said in a statement there's no need for panic ... insisting her father has not received any new bad news -- and is simply regulating his medication.

"I will be there for New Years and promise to post some pictures," Kely Nascimento said Wednesday. "Really and truly, we appreciate the concern and love!!"

Pele initially had a tumor removed in Sept. 2021, and underwent chemotherapy treatments a short time later.

He's often kept a positive attitude throughout his battle, saying in a video message on his birthday last month that "life is good."
