Andre Ward has successfully defended his WBC-WBA super middleweight titles, defeating Chad Dawson on Saturday.
The 28-year-old knocked down Dawson three times before winning on a technical knockout in the 10th round.
Ward knocked down the 30-year-old first late in the third round and then early in the fourth, as he took control of the fight.
The American boxer then finished off his compatriot with a combination at 2:45 of the 10th.
The fight was held in Ward's hometown of Oakland, with Dawson having dropped down a division to challenge the Boxing Writers Association of America's fighter of the year.
