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" move 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).
