Former champion Amir Khan will fight undefeated American light-welterweight Danny Garcia on July 14 for the WBC title. The Briton\'s rematch against Lamont Peterson, scheduled for Saturday, was called off after Peterson, who beat Khan in controversial circumstances to win the WBA super-lightweight and IBF light-welterweight titles, failed a drugs test. Peterson has appealed against his failed drugs test and Khan is still waiting to find out whether or not he will be given back the belts he lost in the defeat. Should that happen, or the titles be declared vacant, Khan\'s fight against Garcia, which will take place in Los Angeles or Las Vegas according to Khan, could be a unification contest. \"It\'s a good fight for me, Danny Garcia is unbeaten in 23 fights and has 14 knockouts so it will be a tough test for me,\" Khan told Sky Sports.\"It\'s a great match-up, the WBC title will be on the line which I\'d love to win. We don\'t know what\'s going to happen to the other two titles at the moment because the hearing will be in the next couple of weeks and then the govening bodies will make their decision.\" Khan said he was still frustrated at being deprived a chance to avenge his defeat by Peterson, who was awarded a split-decision after Khan was docked two points.
