Argentina's Sergio "Maravilla" Martinez, who reclaimed the WBC middleweight title last weekend by defeating Julio Cesar Chavez Jr. in Las Vegas, broke a hand during the fight and will be operated on in Spain for a knee injury.

Promoter Lou Di Bella announced that, besides the broken hand, Martinez suffered an injury to the ligaments in one of his knees, probably produced by a fall he took near the end of the fight.

The 37-year-old Argentine boxer was admitted for several hours to a Las Vegas hospital. Members of his team said that the seriousness of the injury will be determined in the coming days, when the inflammation subsides and it can be examined more closely.

"His hand was broken, he got knocked down, his knee was messed up, but he got up and he didn't look to hold. He looked to fight," DiBella told ESPN. "Sergio Martinez is a man's man. He could have held and grabbed Chavez, or just stay away, but that is not who he is. He wanted to fight to the end and knock the kid out."

After being handily outboxed by his rival during the fight's first 11 rounds, Chavez Jr. harshly punished the Argentine in the last round and was just a hair away from knocking him out. EFE
