MGM Grand, Las Vegas - Ruben Guerrero, father and trainer of Robert 'The Ghost' Guerrero (32-2-1, 18KOs), is expecting his son to dominate undefeated WBA 'regular' welterweight champion Keith 'One Time' Thurman (24-0, 21KOs) on Saturday night in the NBC televised main event of the debut edition of 'Premier Boxing Champions.'

Thurman has been chasing the opportunity to face Guerrero for a long time. Now he's going to get his shot. But, Ruben believes Thurman made a bad career choice in accepting this fight. He feels 'The Ghost' is going to put in a performance that is so dominating - that Thurman is going to consider the possibility of changing his career.

"We're going to find out [what he's made of], because that's the worst thing he did [in signing for this fight]. We're happy he signed he contract. He made a mistake signing that contract. He's going to find out why when he gets in the ring with a six time world champion. We've been there six times, he hasn't. He going to need to do something else after this. Maybe he can be a politician, because he's a good talker. Maybe he can be a politician or change his name to 'One Time' runner," Ruben told BoxingScene.com.
