Even by Vegas standards, it was an unusual weekend. Johnny Football and Gronk frolicked together and then, in the most ill-advised move of the holiday weekend, rapper T.I. got into a fight — with Floyd Mayweather Jr.

The undefeated champ, pound-for-pound the best fighter out there, was dining at a Fatburger establishment with companions when T.I. “walked up and started jawing at Floyd,” according to TMZ. The rapper then “took a swing” at Mayweather and mayhem — including the throwing of chairs — followed. (There allegedly is video here and it contains strong language). The two allegedly had a run-in earlier, when Mayweather yelled at T.I. to “control” his wife, Tiny. There is, of course, video of that incident. (It, too, contains strong language.)

On Sunday, Mayweather offered an explanation, saying that T.I. was angry because Tiny had posted a photo of herself with Mayweather earlier this month and another with Mayweather’s daughter over the weekend. “I’m eating at Fatburger and next thing you know, he walk in talking about we need to talk again,” Mayweather said, denying a relationship with Tiny. “Then a couple of words exchange and people got to pushing and a riot kinda broke out. And then a bunch of chaos and that was basically it.”

Mayweather went on to offer an apology — to Tiny. T.I. illustrated in a short Instagram post that he does not have “two black eyes” from the fight, but he admits that he “[messed] my hand up. That’s about it.” One minor injury and an uncooperative witness were reported at the scene by police.

As for the weekend’s other big event, New England Patriots tight end Rob Gronkowski and Cleveland Browns rookie quarterback Johnny Manziel managed to bond before the UFC 173 card.
