RAF 13 live blog: Colby Covington vs. Belal Muhammad

This is the RAF 13 live blog for Colby Covington vs. Belal Muhammad, who wrestle for the RAF cruiserweight crossover championship this Friday at the Watsoc Center in Miami, Fla.

A former UFC interim welterweight champion, Covington was an NCAA All-American and JUCO national champion in wrestling in college, and earlier this year, "Chaos" retired from MMA so he could compete in RAF full time. With a 3-0 record in RAF, Covington got a chance to wrestle Arman Tsarukyan for the inaugural RAF cruiserweight crossover title, winning 5-3 in a tight contest. Now he's first title defense comes against a man he feuded with in MMA, though the two never fought.
