Fans looking forward to the Jake Paul vs. Mike Tyson fight will have to wait a bit longer -- the July 20 bout has just been postponed following the boxing legend's recent airplane medical scare.

Jake's Most Valuable Promotions just made the announcement ... saying after meeting with medical professionals over his ulcer flare-up on Thursday, Mike was told it was best to do "minimal to light training over the next few weeks."

Taylor Momsen -- the frontwoman for The Pretty Reckless band and one-time "Gossip Girl" star --must be feeling pretty rock 'n' roll right now ... 'cause she got bitten by a bat onstage.

Taylor -- who came up as an actress on 'GG' and as Cindy Lou Who in "How the Grinch Stole Christmas" -- was performing while opening for AC/DC in Spain, when a wild bat flew down and bit her on the leg.

The singer didn't even realize what had happened ... until members of the audience started pointing at her leg -- where the bat had latched on. The video is wild ... you gotta see it -- not to mention the aftermath.

Darryl Strawberry's back to feeling 100 percent --- and he couldn't be happier about it ... revealing to TMZ Sports this week he nearly died from the heart attack he suffered in March.

The Mets legend opened up to us about his medical scare while out in NYC ... and he said things got so bad with his heart at the time of the emergency, doctors couldn't believe he survived.

"My heart was pumping at 40 percent," said Strawberry, who described the heart attack as a "massive" one. "So, there was a lot going on. There was not a lot of blood flowing through my heart at that particular time."

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.

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.

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.
