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.

Jake says people "love to make s**t up," but reassured fans the July 20 bout is still a go. As he put it, "nothing changed."

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.

Devin Haney's father Bill Haney, who also serves as his coach, wants Ryan Garcia out of the sport of boxing forever ... telling TMZ Sports he believes the star fighter's flunked drug tests should lead to a lifetime ban.

Bill made the comments to us on Friday ... some 24 hours after Garcia's B-sample came back positive for Ostarine -- a banned substance. His A-sample previously tested positive for the same PED weeks prior. Garcia initially took the tests on April 19, the day before he beat Devin in an instant classic at the Barclays Center in New York.

Bill said the two tests show Garcia is, indeed, a cheater -- and he's now calling for boxing to turn its back on the 25-year-old for good.

Mike Tyson might be 30 years older than Jake Paul, but that won't stop El Gallo from going for the kill if the opportunity presents itself on July 20 ... telling TMZ Sports there's no chance he takes it easy on the boxing legend in their upcoming fight.

The combat sports community is torn on who's got the upper hand in the Paul vs. Tyson bout -- Tyson is obviously one of the greatest to ever do it, but he's decades removed from his dominance ... while Paul is far less experienced, but in his prime when it comes to age.

We spoke with 27-year-old Paul as the big day rapidly approaches ... and asked if there's any part of him that would hold back based on the fact his opponent is a few years from being a senior citizen.

Logan Paul is going head-to-head with Ryan Garcia ... but not in the ring -- the WWE Superstar's Prime Hydration just hit the boxer with a defamation lawsuit.

The Maverick aired his frustrations on social media just minutes ago ... claiming his drink company is "under attack" by false narratives being thrown around on social media -- and it's time to take action, with King Ryan being the first on his list.

"Today we begin to hold those accountable who’ve damaged our brand for attention while we correct the narrative," Paul said on Instagram. "We're here to stay and will continue to change the world of hydration with bold flavors and creative innovation 📈."

Everyone knows kids can be cruel, but nowhere was that more evident recently than in a video making the rounds on social media showing a boy getting choked out by an adolescent bully.

Check out the horrific footage posted to X by MMA Fighter Dillon Danis ... the vid opens with the bully coming up behind the boy as someone else films them.

The bully then orders the boy to tilt his head back before putting him in a headlock. The helpless youngster asks for the bully to stop if he says to.

If Ricky Stenhouse Jr. and Kyle Busch wanna take their beef from garages and pit roads to an actual squared circle ... TMZ Sports has learned Celebrity Boxing is more than willing to put on the bout for them.

Drake's losses are coming at a fast and furious clip -- the embattled rapper/sports gambler put more than half a million down for Tyson Fury to win his boxing match ... and, he did not.

It's debatable who's in more pain this morning ... Drake or Tyson, after the boxer lost to Oleksandr Usyk by a split decision Saturday night in Saudia Arabia. Prior to the bout, Drake posted his $565,000 wager backing Tyson, and IF he'd won ... Drake would've won $1 million.

Shoulda woulda coulda ... the massive financial blow has fans buzzing about the ol' "Drake curse" in the sports world.

52-year-old Shane Mosley hasn't fought in over 8 years, but the boxing legend's coming out of retirement -- for one fight, at least -- and the Hall of Famer is looking for a celebrity to share the ring!

"I want to announce that we just signed to do an exhibition fight with the official Celebrity Boxing," Mosley said, adding, "I will be stepping back in the ring in August or September."

Ring announcer Dan Hennessey is putting down his mic for good ... he says he's done with the gig after he was dragged for declaring the wrong winner at a big fight last weekend in Australia.

The blunder happened on May 11 at the RAC Arena in Perth ... just after Cherneka Johnson and Nina Hughes went toe-to-toe against each other for 10 rounds with the WBA bantamweight belt on the line.

Hennessey read the three judges' scorecards ... but, he said Hughes won -- when the real winner was actually Cherneka.

Middlewieight boxer Sherif Lawal has passed away after collapsing in the ring following a knockout punch in his professional debut in the UK.

Evander Holyfield had a run-in with an overeager fan after a meet and greet in Los Angeles last month ... and when the legendary boxer wouldn't sign for the guy, he began following The Real Deal, prompting a call to police.

The incident went down in Duarte -- a city in Los Angeles County -- on April 27 ... just minutes after the event, meant to be a cool opportunity for fans to interact with one of the best boxers ever, wrapped up. A fan approached Evander and tried to get some memorabilia signed. When he refused (the guy was given a signed 8x10 photo instead), things took a nasty turn.

We're told the man started to follow Evander, on foot, and then in his vehicle ... as Holyfield's driver attempted to get away.

Influencer and boxer Tristan Hamm -- famously known for knocking out a Logan Paul look-a-like -- is ready to put ex-NFL star Le'Veon Bell to sleep in the ring this month ... telling TMZ Sports he wants Dillon Danis next!!

Hamm and Bell are slated to fight on the Misfits Boxing card on May 25 at the NRG Arena in Houston, Texas ... and Tristan says he's ready for the challenge ahead, despite his debut being just six months ago against Rodney Petersen (you may know him from his run-in with Nate Diaz).
