Ekaterinburg, Russia:   Tonight at the DIVS Sports Palace in Ekaterinburg, Russia undefeated WBO, WBA and IBF Light Heavyweight World Champion Sergey "Krusher" Kovalev (30-0-1, 26 KOs) dazzled his hometown crowd during 12 heart stopping rounds as he defeated Isaac "Golden Boy" Chilemba (24-4-2, 10 KOs) via unanimous decision.

The hard-fought battle between Kovalev and Chilemba was non-stop action from bell to bell. Kovalev came out of the gates guns blazing but the tough Chilemba took every punch handed out by the hard-hitting champ.

The toughest round for the 29-year old Chilemba was the 7th when he was knocked down by the Krusher. Chilemba managed to recover and last the remainder of the fight.

Isaac is only the second fighter to go the full 12 championship rounds with Kovalev (Bernard Hopkins was the first, Nov. 8, 2014, which Kovalev won by UD). However, it was not enough to secure the victory against the more powerful Kovalev.

The judges handed the victory to Kovalev (117-110, 116-111, 118-109).

And still the WBO, WBA and IBF Light Heavyweight Champion, Sergey Kovalev said: In his preparation for the fight, Kovalev continued, "There were obviously some moments during the training with regards to my health, because I got a cold and I didn't say anything, so the information wouldn't get to Chilemba, that it might work against me. So myself and my trainer worked hard to overcome this stage and prepared for the fight."
