Britain's Anthony Joshua retained his IBF heavyweight crown by knocking out American Dominic Breazeale in the seventh round at London's O2 Arena on Saturday.
Unbeaten Joshua dominated from the start but the 30-year-old Breazeale proved a durable opponent, absorbing some thunderous blows from the 2012 Olympic champion before succumbing.
There were signs that Joshua was getting frustrated in the sixth round but he began the seventh with a tremendous attack that sent his opponent to the canvas.
Breazeale, also unbeaten prior to this bout, managed to continue but was floored again by a left to end the contest.
Joshua took his record to 17-0, all by knockout.
