Unbeaten light-heavyweight world champion Artur Beterbiev stopped Britain’s Anthony Yarde in a thrilling eight rounds at London’s Wembley Arena on Saturday to retain his WBC, IBF and WBO belts. The Russian-born Canadian sent the Briton to the canvas with a punishing right and, after a standing count, the challenger’s corner signalled to the referee to stop the fight two minutes and one second into the round.
