Ailin Perez got the better of Norma Dumont on the scorecards in the co-main event of UFC Vegas 121, but the fight almost didn't end cleanly. According to MMA Fighting, multiple members of security had to step in right after the final horn sounded to keep the situation from escalating between the two bitter rivals.

The result itself was a unanimous decision for Perez, closing out a grudge match that had been building for a while. Our tracker had Dumont ranked one spot ahead of Perez at bantamweight, number four to Perez's number five, and the Elo numbers back up just how tight this one was on paper, with Dumont sitting at 1596 and Perez at 1590, both built off eight tracked bouts. It was the kind of matchup where the numbers said close fight, and the finish backed that up in the ugliest way possible.

The aftermath is what has fans talking now. One Reddit thread getting attention claims Dumont threw condoms and dollar bills at Perez in the chaos that followed the decision, a detail that has fueled plenty of reaction online even without official confirmation from the broadcast. Another thread pointed out that Dumont's reaction to the loss looked strikingly similar to how she responded to a previous defeat, though the specifics of that comparison are still being hashed out by fans rather than confirmed by anyone at the event.

Whatever exactly triggered the security intervention, the sporting stakes are clear enough. Perez comes out of this with a decision win over a fighter our data had ranked ahead of her, a result that should keep her firmly in the bantamweight mix, while Dumont now has to regroup after dropping a fight many expected to be a coin flip.
