Nurse!

Comedian D.L. Hughley had some sort of medical emergency Friday night ... he was performing at a Nashville club when he went limp and passed out cold.

D.L. was performing at Zanies Comedy Club and a sold out crowd was enjoying his jokes when suddenly, at around 11 PM, it appeared something was amiss. His speech became labored. A security guard handed D.L. a bottle of water, and a minute later he just passed out cold while he was leaning against a stool.

The comedian's manager was at the ready and grabbed D.L. to break his fall. The manager carried him off stage and that was it ... no one told the crowd what happened, but it was serious enough for an ambulance and fire truck to show up. D.L. was put on a stretcher and taken to a nearby hospital.

We've tried contacting D.L.'s rep ... so far, no word back.

The imagery brings all the worry to life ... thousands of people are lined up outside the Tulsa venue where Donald Trump will hold his campaign rally Saturday night, and it's hard to spot masks in the crowd.

The venue itself will hold around 19,000 people ... all of whom will sit inside for hours waiting for the rally to begin. City officials say as many as 100,000 people may turn up for the event. As we reported, doctors believe just based on the people who get inside the venue ... 800 to 1,000 will contract the virus.

Trump's anti-mask message has clearly connected with his followers, despite the clear science that masks help prevent the spread of the virus.

Authorities are expecting protesters at the rally ... one's already been arrested for trespassing, despite the fact she was peacefully protesting. And, Trump has dog whistled on Twitter that some of the protesters -- or as he calls them "lowlifes" -- will be met with violence if they dare make their presence known.

Here's video footage of Lamar Jackson tumbling over a jet ski and into ocean water in a beach football game over the weekend ... and we gotta say, it's terrifying!!!

The NFL MVP was getting in a little run with his bros on the sand ... when he started doing Lamar Jackson things.

The clip is pretty crazy ... Jackson's acceleration from zero-to-sprint is INSANE -- but when he finished off the run, John Harbaugh and ALL of Ravens nation couldn't have been happy.

Check out the clip, Jackson tumbled and dove headfirst over a waverunner ... and it's maybe the scariest hit he took in all of this past calendar year.

Fortunately, LJ came up from the fall just fine ... but, man, SHEEESSSSHHHHH!!

Of course, beach football injuries are VERY real ... remember, star NFL running back Robert Edwards completely shredded his knee in an infamous sand game back at the 1999 Pro Bowl.

Univ. of Texas star defensive back B.J. Foster won't have full use of one of his hands for a bit ... his coach says he broke it punching his car in a fit of anger.

Tom Herman told reporters Thursday the junior came out to his vehicle in a parking lot ... and when he saw it had been hit (plus, the other driver didn't leave a note) -- he exploded.

"He got a little angry and decided he was going to take it out on the car bumper," Herman said.

The result? The coach says Foster broke the fifth metacarpal in his hand punching the ride and will require a cast to heal the injury.

"We had a long conversation on that," Herman said. "Every time, in my 45 years on a planet, when a player gets in a fight with an inanimate object, usually the inanimate object wins."

Good news, though ... Herman says Foster will still be able to work out with the Longhorns despite the cast -- and is expected to make a full recovery in time for the season.

Tony Hawk is proudly showing off the wild x-rays from his most recent skateboarding accident ... saying docs had to cut his wedding ring off in order to put his fingers back in place.

Of course, the GOAT revealed he dislocated his fingers in a nasty accident over the weekend ... when he was skating with his son and some friends at an empty backyard pool.

"The session was fun until I did a backside smith stall as a set up for a backside blunt, and suddenly found myself on the flat bottom with my fingers bending in new directions," Hawk said at the time.

Hawk was rushed to the hospital to get his fingers locked back into place ... and luckily, he's gonna make a full recovery.

Now, the 52-year-old has some new souvenirs in the x-rays following the debacle ... and the way he describes what the docs had to do is CRINGE.

"They had to cut my ring off before returning my bones to their full upright and locked position. My fingers are still sore / stiff / swollen but mostly functional."

But, if you think this is gonna stop Hawk from skating again ... you're DEAD wrong.

Buffalo Mayor Byron Brown held a news conference discussing police action against protesters in his city ... including the 75-year-old man who was knocked down by Buffalo cops

The Mayor said NY State Troopers had arrested one man he described as a "key and major instigator" of people who were looting and/or vandalizing.

He also addressed the police brutality against Martin Gugino by laying out the instructions Buffalo cops were given regarding dealing with protests.

Mayor Brown said officers were told to be careful and "protect our residents, protect peaceful protesters and use common sense." He said he would not call for the firing off the 2 officers involved in the Gugino incident, and wanted them to have due process.

As you know, Gugino was standing all by himself when he was shoved to the ground, and left bleeding from the head and ear.

As we reported, 57 other officers resigned from Buffalo's Emergency Response Team in solidarity with the 2 cops who were suspended for the incident.

Gugino remains hospitalized, but his attorney says he is "alert and oriented."

The entire Emergency Response Team at the Buffalo Police Department has resigned in a show of solidarity for the cops suspended for shoving an elderly man to the ground.

A total of about 57 officers walked off the job Friday, though they are still employed with the police department -- just no longer on the ERT ... according to WIVB reporter Dave Greber.

The move comes less than 24 hours after video surfaced showing cops in heavy gear shoving 75-year-old Martin Gugino even though he was NOT being physically confrontational. A rep for Buffalo PD allegedly told a lcoal reporter the man was injured when he "tripped and fell," but the video shows that's clearly not the case.

Gugino started bleeding from his head and lay motionless immediately after his head hit the pavement.

MMA legend Wanderlei Silva says he's lucky to be alive after getting hit by a car -- AGAIN -- while riding his bike in Curitiba, Brazil.

"I could even have died if I wasn’t wearing a helmet,” Silva told Brazilian media outlet Tribuna.

The 43-year-old legend was biking Wednesday across a large street with two traffic lights ... when something went horribly wrong.

"The first one was green ... but I cannot [be sure] if the second turned red in the process."

Silva says he was thrown from his bike -- suffering cuts on his face and a broken bone in his foot.

"People have to be more careful in traffic. It’s hard to ride bikes in Curitiba.”

If the story sounds familiar, it's because Silva was also hit by a car while riding his bike to his gym in 2016.

Silva suffered major damage in that crash and required stitches on his leg.

Similarly, he credits his bike helmet for saving his life in that incident too.

Great news for skate phenom Sky Brown ... the 11-year-old was able to walk out of the hospital just days after a horrific crash on Monday ... and to make things even better, she got to hang with TONY HAWK!!

The internet sensation suffered skull fractures, a broken wrist, broken hand and a black eye after a devastating fall off a vert ramp on Thursday ... but remained in positive spirits about the whole accident.

The skate GOAT spoke out about the serious accident ... saying, "From my perspective and in many ways, it was the worst fall one could take from a vert ramp," Hawk said Monday.

"The situation was dire and we were all worried sick, but nothing compared to the heartache her family endured that day."

Hawk says he stayed in contact with Brown's family every day since the accident ... and was present to lift her spirits when she got the green light to go home.

"Her accelerated healing is nothing short of a miracle."

Hawk says he joined Brown for a celebratory ice cream sesh to cap off the big achievement ... and shared a positive message to the rising star during her recovery.

"Stay strong, Sky. Thank you for inspiring us with your unbroken spirit. And please take your time getting back to full capacities… we’ll gladly wait for you."

Warning -- this is VERY hard to watch.

11-year-old skateboarding sensation Sky Brown was rushed to a California hospital Thursday after crashing to the ground during a ramp trick gone wrong.

Brown suffered skull fractures, a broken wrist, broken hand and a black eye ... but somehow, she's in amazing spirits about the whole thing and posted an update Monday from her hospital bed.

"I don’t usually post my falls or talk about them," Brown said ... "but this was my worst fall."

"And I just want everyone to know that its okay, don’t worry I'm okay."

"I'm just gonna get back up and push even harder."

Brown has been pushing to make England's skateboarding team when the sport makes its Olympic debut at the Tokyo Games in 2021.

Her father spoke with the media and described the incident -- saying "Sky landed head-first off a ramp on her hand."

"When she first came to hospital, everyone was fearful for her life."

Sky's dad noted she's "lucky to be alive" -- and "she remain positive and strong."

"The whole medical team is shocked to see her positivity."

Tony Hawk commented on Brown's post Monday -- saying, "Worst day ever. Hope your surgery went well today."

A huge snake clamped onto a woman's hand, and then tried to put a death grip on her arm and leg in a matter of seconds ... and the whole battle is on video.

Check out this gnarly clip showing a woman -- who seems familiar with the python -- get attacked as soon as she lets it out of its tank. The snake bites down on her hand and then starts to curl itself around her entire arm.

At first, she tries to keep her cool and almost acts as if she's gonna handle the sitch on her own -- but things quickly escalated as the python wrapped itself even tighter, which prompted her to ask for help. Too little, too late it would seem.

Just a few seconds later, the snake latched onto her leg and started to coil even more ... which sent the woman into panic mode -- not to mention the guy who's trying to get it the hell off of her. Amid the chaos, the video finally cuts out.

It's unclear where or when exactly this happened, or what happened after this whole mishap -- but on its face, the message seems clear ... do NOT play with pythons!!!

As Indiana Jones once said ... anything but snakes 😬

Jason Derulo's heading back to the dentist, 'cause he's gone and chipped his teeth again -- for real this time, it seems -- with a crazy stunt involving corn ... and a power drill.

The singer was attempting to nosh on some kernels, straight off the cob, by employing what he called a "life hack" -- apparently, people have been stabbing corncobs onto drill bits and pulling the trigger to rotate it and eat it faster. All for the love of TikTok. Really.

Welp, it turned out to be more of a tooth hack than anything else for JD -- who quickly screamed out in pain as he was revving it up, only to pull back and reveal his 2 front teeth got snagged clean off by the spinning cob.

It looks SUPER painful.

We should note ... Jason had another major missing-tooth incident just earlier this month -- a fake one, apparently -- when he did a handstand by his pool. When he fell in he emerged to show he'd "broken" one of his front teeth.

A word of advice for Jason, who seems to be getting a little too much of a kick outta these gross-out teeth vids ... CHILL, BRO! That, or invest in sturdier chompers. 😬

An E.R. doctor, who goes by Dr. Bill, is irate that the federal government is spending millions of dollars on Blue Angels flyovers while medical workers have to wear painters masks and the hungry go without food ... and he says it's all to make President Trump look good.

Dr. Bill didn't say where he works, but he's pissed at the flyovers by the Blue Angels and Thunderbirds, which salute health care workers in various cities.

The doc says it costs $450k for one Blue Angels flyover and another $450k for the Thunderbirds. The Air Force and Navy pilots have been buzzing various cities, drawing big crowds from below, but Dr. Bill says it's a shameful waste of money.

He holds up a painters mask with contempt, noting they don't provide nearly the protection of the scarcer N-95 masks. He's also ticked off some of the essential services that could be funded in lieu of flyovers.

UFC star Anthony Smith says he's "good" in the wake of a violent loss to Glover Teixeira -- and recovering with the help of his loving family.

"Everyone is arguing about good stop, bad stop, bad corner, good corner...blah blah blah," Smith said.

"I’m still winning. I’m good, and I’m exactly where i need to be, doing exactly what I’m supposed to be doing."

As we previously reported -- Smith suffered intense injuries during his fight on May 13 -- a broken nose, fractured eye socket, a gash under his right eye and had 2 teeth knocked out.

Some high-profile UFC stars like Chael Sonnen have criticized Smith's coaching staff ... saying they should've thrown in the towel instead of allowing him to fight in the 5th round, where he sustained even more damage.

"All that time spent worrying about me needs to be spent somewhere a little more productive," Smith said on social media.
