Bulgarian challenger Kubrat Pulev (20-1, 11 KOs) proved to be too weak in the chin tonight in getting stopped in the 5th round by IBF/IBO/WBA/WBO heavyweight champion Wladimir Klitschko (63-3, 53 KOs) at the O2 Arena in Hamburg, Germany.
Pulev was knocked down four times in the fight from left hooks. He was down twice in the 1st, once in the 3rd and a final time in the 5th. Referee Tony Weeks stopped the fight at 2:11 of the 5th after Wladimir put Pulev down with a left hook to the head that put Pulev down on his back. The shot caused a huge swelling under Pulev’s right eye.
