After Derrick Lewis knocked out Travis Browne at UFC Fight Night 105 on Sunday, he was happy to add insult to injury. Noting that Browne, Ronda Rousey’s longtime boyfriend, has been accused of domestic violence by his ex-wife, the victorious heavyweight made his own bid for Rousey’s affections.

“I just knew I had a bigger heart than [Browne],” Lewis, nicknamed “The Black Beast,” said in the Octagon right after his win. “He call himself a man, but he likes to put his hands on women. So, forget that guy. I got much more heart than he has.

“Where’s Ronda Rousey’s fine a– at?”

Lewis (18-4) ended matters against Browne (18-6-1) in the second round after knocking the latter to the canvas, then raining blows on his opponent’s face. Some observers thought that the referee took too long to stop the fight and caused Browne to endure excessive punishment.

Elsewhere in his post-fight interview, Lewis responded to a question about taking some damaging first-round kicks to his midsection by saying, “I just gotta do number two, that’s all. It’s not really hurt from the kick. I just got a boo-boo.”

As far as his immediate future, the up-and-coming heavyweight said he needs to take a bit of a break, explaining, “All the training and all the sex I’ve been getting, my body needs some time off.”

It’s been a tough stretch, at least in the Octagon, for Browne and Rousey, who herself was knocked out in just 48 seconds by Amanda Nunes in her long-awaited comeback at UFC 207 in December. The pair have been dating since at least August 2015, not long after Browne’s then-estranged wife (they got a divorce in February 2016), Jenna Webb, accused him of domestic violence.

Webb, a fitness model, posted photos online that showed bruises on her body, and she wrote, “Probably one of the hardest decisions I’ve ever made was walking away from this life and starting over. I’m still ashamed for staying as long as I did.”

Browne has repeatedly denied those accusations, but at the very least, they have provided fodder for his UFC rivals. In Lewis’s opinion, they also provided grounds for Rousey to leave Browne for a man who thinks he’s proven himself superior both in and out of the Octagon.
