Cosmopolitan, Las Vegas - In a light heavyweight contest, prospect Trevor McCumby (24-0, 19KOs) picked up the biggest win of his career with a first round destruction of Donovan George (25-7-2, 22KOs).

McCumby took the fight straight to George and seemed to hurt him with every punch. A big shot to the head sent George down. He beat the count, but then McCumby steam-rolled him with a big barrage of punches that sent him down hard for a second time.

Once George fell down on his back, referee Robert Byrd quickly waved off the contest.

Junior welterweight Maxim Dadashev (5-0, 4 KOs) stopped Efrain Cruz in the second round. After a competitive opening round, Dadashev began to land repeatedly onto Cruz in round two.

A barrage of punches momentarily stunned Cruz (4-3-1, 1 KO) midway through the round. Moments later, another accumulation of punches from Dadashev dropped Cruz onto the canvas, prompting referee Kenny Bayless to wave the fight over at 1:57. 

Welterweight prospect Juan Ruiz scored an impressive first round knockout win over former fringe lightweight contender Fernando Carcamo.

Thirty seconds into the opening round, Ruiz (18-0, 11 KOs) dropped Carcamo with a left-right combination to the head. Carcamo (21-8, 16 KOs) attempted to fight back, but would get stunned repeatedly with right hands to the head. A counter right to the head dropped Carcamo to the canvas, prompting referee Robert Byrd to stop the bout at 2:43.
