UFC fighter Derrick Lewis knocked out Travis Browne, boyfriend of Ronda Rousey, last night at UFC Fight Night 105 and then added insult to injury during his post-match interview in the center of the octagon.

First, Lewis referenced the fact that Browne had been investigated for domestic violence a few years ago, saying he has much more heart than a guy who likes to put his hands on women.

Then, he called out Browne's girlfriend, Rousey.

While Browne was being taken to a hospital for injuries sustained during the fight, Lewis grabbed the mic and said, "Where Ronda Rousey fine ass at?"
