Mixed martial artist Dean Thomas is used to knocking people out. Now, he's offering to knock out singer Chris Brown for Rihanna.
After he won at the March Badness MMA and boxing event, he grabbed the microphone and told the crowd that it is not cool to put your hands on a woman.
He went on to say that if Rihanna wants someone to kick Brown's butt, she can call on Thomas to get the job done.
Brown is accused of assaulting Rihanna after the couple reportedly had a fight.
