Nicholas Walters (25-0, 21KOs) became a major player on Saturday night, when he knocked out Nonito Donaire with a second left in the sixth round at the StubHub Center in Carson, California. Donaire (33-3), who dominated smaller fighters in the lower weight divisions, was dominated by a much bigger man.

Against Walters, Donaire was dominated for the most of fight. He did catch Walters at the end of the second to seriously hurt the Jamaican boxer. But then Donaire went down in the following round from an uppercut. At the end of the sixth, Walters landed a huge overhand right to the side of Donaire's head, causing him to fall face-first and barely able to beat the count before the fight was waved off.

Donaire is not sure what he's going to do next, as he admits that big featherweight like Walters are too big for him.

"I've got to go back to the drawing board," Donaire said. "I know I can't compete with guys like Walters. I never back down from any fight. I could’ve said I don’t need to fight this guy. I’ve got the WBA [title]. But he beat the sh*t out of me.”
