Gavin Rees loses out to American star Adrien Broner who retained World Boxing Council lightweight title Broner's victory - he is unbeaten now in 26 straight fights - paves the way for a unification showdown with Scotland's World Boxing Organisation title-holder Ricky Burns, who fights Mexico's International Boxing Federation champion Miguel Vázquez on Mar 16. Broner said he that would like to fight Burns afterwards, adding that Rees was "world class but [looked] like a cooked steak" after he had finished with him. Rees, the 32-year-old former light-welterweight world champion from Newbridge, an 18-1 outsider, started fast and won the opening round. However, he then met the speed - and spite - of the 23-year-old Broner, who floored the challenger twice before trainer Gary Lockett pulled his man from the contest in the fifth with Rees hurt and under fire. Broner had taken control clinically in the third round by landing a flurry of hurtful hooks and a big uppercut with a minute remaining and then floored Rees in the fourth with a right uppercut. When Rees went down on one knee from a body shot in the fifth, his corner pulled him out twenty seconds later as Broner set about him, landing heavy shots with ease. "He was catching me with some great shots and the game-plan went out of the window," Rees said." When you're stunned you don't think properly. I'm a warrior, I'm always going to get back up. I'd have carried on until he knocked me out cold. He's the best I've been in with. He's world champion for a reason. I made a lot of mistakes.
