Nurse!

Bill Moseley -- known for 'The Texas Chainsaw Massacre' franchise -- got an unwelcome scare of his own last week after being slammed into by a cyclist ... who apparently took off.

The actor's rep tells TMZ ... it all went down in Raleigh, NC Friday -- where the horror icon was expected to attend Carolina Fear Fest ... but shortly before the event kicked off, he was hit from behind during an afternoon walk, leaving him with 4 fractured ribs and a fractured pelvis.

We're told Bill was walking behind his hotel along a dual pedestrian-bike path and that a dude came flying down the lane and ran right into him from behind ... at a speed which we're told was about 30 MPH. Rather than stop to help, Bill's rep says this man bolted ... fleeing the scene.

Bill, as a result, was left writhing in pain ... and we're told help was eventually called for him ... and he was transported to a trauma hospital, where he underwent multiple CT scans.

In the end ... Bill suffered multiple pelvic and rib fractures -- something he noted himself on IG, posting a couple shots of himself in a hospital gown, and eventually being wheeled out in a wheelchair. While what happened to him was serious ... he's keeping his spirits up.

As for the biker who hopped back on his bike and rode off, Moseley -- who's also starred in 2007's "Halloween" threw in a horror character reference, saying ... "And here I thought Jason packed a punch!"

Bill's since been discharged from the hospital, and has a 6-week rehab stay ahead of him, and has been ordered by docs to avoid putting weight on his left leg at all costs.

The folks behind Carolina Fear Fest also confirmed Bill's expected to make a full recovery, and have announced anyone who purchased a photo op with Bill will receive an immediate refund.

Bill's undoubtedly loved and respected in the horror community. In addition to starring in the 1986 sequel to "The Texas Chainsaw Massacre," he also appeared in "Texas Chainsaw 3D" in 2013 as Drayton Sawyer.

He's also a staple in Rob Zombie's "Firefly" trilogy, among countless other horror projects solidifying his status as a genre icon.

10:10 AM PT -- Jake Paul is shutting down any online chatter about their fight being called off in the wake of Mike Tyson's health scare.

Mike Tyson is recovering from an ulcer flare-up he suffered while flying cross-country -- and it was so bad, airline staff had to put out the call for any medical professionals on the plane to come forward.

Sam Mouzer's getting real about the uniquely terrifying pest control he went through on "Naked and Afraid' -- just in case you've ever wondered what it takes to get a tick off your junk!

We spoke with the super unlucky 'Naked and Afraid' contestant after getting a sneak peek of this Sunday's episode where a tick burrowed its way into Mouzer's manhood, and we had to ask about the procedure for yanking a parasite from such a sensitive spot.

Sam says the medic examined his penis before pulling out a "bladed device" to exterminate the little beast -- an image ghastly enough to make anyone with a penis shudder

"Naked and Afraid" contestant Sam Mouzer is convinced he's cursed -- or at least his penis is -- after suffering another phallus injury ... and this one's more gruesome than the first!

TMZ got an exclusive look at Sam's return to the franchise -- this time he's on "Naked and Afraid XL" -- and he wasted no time making history yet again, as the clip shows him getting a "d**k tick" while out in the Colombian Badlands.

It would be a painfully remarkable event, no matter whose junk picked up the little hitchhiker -- but Sam makes it, well ... maybe the worst luck of all time.

NASCAR driver Ricky Stenhouse Jr. going all Mike Tyson on Kyle Busch at the All-Star Race just set him back financially -- he was just fined $75K for his involvement in this past weekend's wild brawl.

The racing organization handed down the punishment on Wednesday ... saying not only will RSJ have to write out a hefty check, but his dad was suspended indefinitely for his role in the scrap as well.

As we previously reported, the two drivers confronted each other after Sunday's event ... with Stenhouse pissed after Busch seemingly caused him to wreck on purpose at the beginning of the race.

Nina Dobrev's active lifestyle has taken a hit -- 'cause she landed in the hospital ... this after an accident on an electric bike.

Nina appeared to blame an e-bike for her current state ... as her first slide in the upload featured her posing on the vehicle in a little black outfit -- looking as happy as can be.

Paul Pierce is finally letting the world know how he suffered a finger injury that required a trip to the hospital last week ... revealing he busted up the digit during a workout mishap.

The NBA Hall of Famer explained the situation to Keyshawn Johnson and Skip Bayless on Monday's episode of "Undisputed," telling the guys it all happened as he was trying to do a plank with a weight on his back last Friday.

Pierce said at one point during the core exercise -- the 45-pounder that had been placed between his shoulder blades came dislodged ... and then fell right on his hand.

Britney Spears says she's healing all on her own after a trip to Mexico -- which she says included cursing out strangers -- but visuals of her battered foot seem to tell a drastically different story.

Late Friday, the pop star posted a disturbing video of her horribly swollen right foot ... there's no way to tell how current the clip is, but in her caption, she claims she fixed it all on her own. As Brit says, "I was stubborn and did it my way !!! I didn't listen to a motherf***ing soul !!"

That doesn't seem like the wisest plan, based on the dark bruising around her heel, on top of the swelling. Remember, this is the injury she sustained during her notorious meltdown at the Chateau Marmont earlier this month.

Warning -- if you're enjoying your Friday supper, ya may wanna put down the quinoa bowl before reading this one.

The two combatants face offer outside a gas station, with machetes and swinging -- steel slashing against steel on the sidewalk. They exchange wild hacks, and, at first, it seems like one man may have the advantage as he forces his opponent to the ground.

Steve Buscemi was captured on video casually walking on the street moments before he was randomly sucker punched by a hulking assailant in NYC.
