The WBC boxing champ Danny Garcia added the WBA light welterweight belt to his collection with a stunning fourth-round upset of Britain's Amir Khan in a unification title fight in Las Vegas.
American Garcia knocked Khan down three times with the end coming with 32 seconds left in the fourth round when referee Kenny Bayless stopped the bout.
Garcia, who already had the WBC title, now has 24 wins and no losses.
Briton Khan suffered just the third loss of his career.
When Bayless stepped in to stop the fight, the 25-year-old Khan protested and tried to duck under the referee's arm.
