IBF super-middleweight champion Jeff Lacy isn't impressed with Joe Calzaghe's 40-0 record.
Calzaghe, 33, owns a big punch, but Lacy said the Welshman hasn't fought much in the past two years.
"I think it's going to take its toll," Lacy said. "I see a lot of weaknesses. He hasn't fought anyone like me."
The left-handed Calzaghe has defended his lightly regarded WBO title 17 times, dating to 1997. He has been frustrated that he hasn't fought for the more prestigious IBF, WBC and WBA belts.
Calzaghe broke his left hand against Evans Ashira on Sept. 10, when he won a lopsided decision while fighting one-handed for the last eight rounds.
The injury postponed the fight against Lacy from November to March.
SUPER-FLYWEIGHT: WBC champion Masamori Tokuyama of Japan defended his title against American Jose Navarro in Osaka, Japan.
Tokuyama scored a unanimous victory over Navarro, the WBC's top-ranked contender, in the 12-round fight. Tokuyama said it will be his last as a super-flyweight.
"I will be graduating from the super-flyweight class," he said. "I will be working hard."
