Gennady Golovkin bids to become a world champion again when he takes on Sergiy Derevyanchenko for the vacant IBF middleweight belt.

Three-division champ and current world featherweight titleholder Leo "El Terremoto" Santa Cruz (32-0-1, 18 KOs) puts his belt on the line against one of the UK's toughest fighters: undefeated Irishman Carl "The Jackal" Frampton (22-0, 14 KOs). Plus, undefeated former two-division champ Mikey Garcia (34-0, 28 KOs) returns to the ring against Elio Rojas (24-2, 14 KOs) and junior middleweights Tony Harrison (23-1, 19 KOs) and Sergey Rabchenko (27-1, 20 KOs) face off in a 12-round eliminator.
