What happened: Askren is booked against Belal Muhammad in Saturday's co-main event. He has said the contest will be the final match of his career.
Why it matters: The booking brings Askren back to wrestling in Wisconsin, where he runs a youth academy. His combat-sports career has spanned wrestling, MMA and boxing.
By the numbers: Askren compiled a 19-2 record with one no contest in MMA. He won consecutive NCAA titles and represented the United States at the 2008 Olympics.
What to watch: RAF 11's co-main event result will close Askren's one-match return.
