Undefeated Luis Arias (18-0, 9 KOs) retained his USBA middleweight belt with a stoppage victory over Arif Magomedov (18-2, 11 KOs) at 1:16 of round five in a scheduled ten-round bout. Magomedov appeared to have the advantage early behind a consistent left jab and lead left hands. Arias though had repeated success with his right hand, particularly to the body, and seemed to be landing with greater frequency as the bout progressed.
