Scottish Exhibition Centre, Glasgow, Scotland - Ricky Burns (35-2, 10KOs) retained his WBO lightweight title with a very impressive fourth round stoppage of Kevin Mitchell (33-2, 24KOs).

It was a boxing match until the final thirty seconds of the first round, when both boxers started trading punches. Burns started landing hard right hands in the second. During the fourth, a crushing left hand sent Mitchell down hard on his back. Mitchell made it up but Burns quickly dropped him again with a barrage of shots. After Mitchell beat the count, Burns pinned him against the ropes and continued to blast away with both hands until the referee stopped the fight.
