Nigerian-born Anthony Joshua retained his International Boxing Federation (IBF), World Boxing Association (WBA) and World Boxing Organisation (WBO) heavyweight titles, with a seventh-round stoppage of Alexander Povetkin at Wembley Stadium in London on Saturday.
Povetkin regained his feet, but Joshua resumed with a barrage of punches.
A previously close contest turned in Joshua’s favour decisively, when he sent the Russian crashing to the canvas, with a straight right hand and left hook.
It forced referee Steve Gray to stop the contest at one minute and 59 seconds of the seventh round.
Victory saw Joshua, the London 2012 Olympic champion, extend his unbeaten professional record to 22 wins from 22 fights, with 21 knockouts.
