The UFC just fired one of its top rising stars -- undefeated Ottman Azaitar -- after he allegedly committed one of the most INSANE safety violations we've ever heard.
Ottman -- who's 13-0 as a pro with some crazy highlight-reel knockouts -- allegedly stole a page out of a "Mission Impossible" movie to sneak an unapproved guest into the Fight Island area on Abu Dhabi, risking the health of EVERYONE there.
FYI, 30-year-old Ottman was scheduled to fight on the main card at "UFC 257: Poirier vs. McGregor" on Saturday night -- taking on 30-year-old Matt Frevola (8-1-1).
But, that fight was removed from the card on Friday due to a "health and safety violation."
So, what the hell happened?! Dana White explained to BT Sport ... and man, the allegation is bad.
"So [Ottman Azaitar] and his team cut off their wrist bands, gave 'em to somebody outside the bubble," White explained ... "I don't know how they even did it."
"That guy taped [the wristbands], showed up here [on Fight Island] with a bag, went into a room, shimmied across 4 balconies, went in [Ottman's] room, dropped the bag off, changed his clothes and then left."
Dana continues ...
"Now, when security tried to stop him, he wouldn't stop either way and yeah it's just bad."
Dana said he fired Ottman on the spot -- "He's gone. He's no longer a UFC fighter and he's not fighting [Saturday night]."
The big question -- what was inside the mystery bag?!!?!? Our UFC sources say they have no clue at the moment. Guessing they're going to try and find out.
As we previously reported, the Fight Island area is incredibly secure -- with multiple COVID testing points and crazy security to keep everyone safe. One violation could compromise the entire thing.
