Top Rank's CEO Bob Arum was unhappy with the officiating in Saturday's main event at the Mandalay Bay in Las Vegas, which saw Brandon Rios (30-0-1, 22KOs) win a controversial twelve round split decision over WBA interim-lightweight champion Richard Abril. The scores were 116-112, 115-112 for Rios and 117-111 for Abril.

"He allowed Abril to hold him the entire fight. He never took any points away. [Mercito] Gesta had a good referee, Robert Byrd. When the Colombian fighter continued to hold him, Byrd told him that he would take away a point and he stopped [holding him]. Then entire fight changed and Gesta knocked him out. Drakulich didn't do that. He let Abril get away with holding Rios without any points being taken away," Arum told BoxingScene.com.
