Hall of Famer Joe Calzaghe won a twelve round split decision over Bernard Hopkins in April of 2008. After the fight, most observers thought Hopkins was finished. Fast forward to more than six years later - Calzaghe is long retired and Hopkins (55-6-2, 32KOs) is still going strong at 49-years-old.

Last August in Walks, Calzaghe watched his close friend, Nathan Cleverly, get demolished by Kovalev in four rounds.

Calzaghe wonders if Hopkins finally bit off a little more than he can possibly chew.

"Hopkins was a great win [for me]. The more he wins, the bigger the win is for me. What a great fighter he is. 49-years of age and still winning titles. That's a dangerous fight [with Kovalev]. I'm not sure about that one. Nathan is a good friend of mine and Nathan says this Kovalev has unbelievable punching power. As a 49-year-old man, is he going to be able to get away for twelve rounds. That's the question and I think it's going to be very difficult for him [to do that]," Calzaghe told BoxingScene.com.
