Arias retained USBA middleweight belt

The end came shortly after a pair of right hooks by Arias seconds apart knocked Magomedov down in round five. The first right hook did most of the damage, causing Magomedov to wobble badly, with the follow-up right hook putting him down. Magomedov got off the canvas but was in trouble again soon after, prompting both his corner and referee Robert Byrd to move in to stop the fight almost simultaneously.
