By Dan Ambrose: John David Jackson, the trainer for IBF/WBA/WBO light heavyweight champion Sergey Kovalev (26-0-1, 23 KOs), thinks one of the biggest reasons why Kovalev was able to beat the 49-year-old Bernard Hopkins (55-7-2, 32 KOs) in their recent fight on November 8th was due to Kovalev keeping his head and not getting frustrated easily when he was unable to score a knockout over Hopkins at some point in their fight.
Kovalev put Hopkins on the floor in the 1st round, and he also hurt him in the 12th. However, Hopkins did a good job of taking Kovalev’s best shots to continue fighting.
