Following the defeat, Rubio was sacked and was replaced by Freddie Roach. Khan began training with Roach at the Wild Card Gym in Los Angeles, training alongside stablemate Manny Pacquiao, the then WBC lightweight champion and pound-for-pound king. On 6 December 2008, Khan scored a comeback win against Oisin Fagan with a second-round stoppage; Khan won the vacant WBA International lightweight title. Khan knocked Fagan down twice in the first round and Fagan's corner threw in the towel after he was knocked down again in the second. Following the fight, it emerged that Fagan had suffered a fractured fibula during the first knockdown.
