MOSCOW (AP) — Denis Lebedev of Russia successfully defended his WBA cruiserweight title when he knocked out Pawel Kolodziej of Poland on Saturday.

Lebedev floored Kolodziej with a left in the second round to keep his title at the Dynamo Sports Palace.

Lebedev (26-2, 20KO) gave Kolodziej his first career defeat after 33 wins.

It was Lebedev's first fight since May 2013. It came after a scheduled rematch against Panama's Guillermo Jones was called off in April when Jones failed a drug test. That rematch was mandated after Jones beat Lebedev for the belt last year, only to test positive for a banned substance on that occasion, too.
