Despite interest in a bout with Khan, Floyd Mayweather announced that he would fight Marcos Maidana (35–3, 31 KOs) on 3 May 2014. On 24 March, Khan decided to fight 32-year-old former champion Luis Collazo (35–5, 18 KOs) on the undercard at the MGM Grand Las Vegas. The fight was for the vacant WBA International welterweight title and WBA title eliminator, as well as the vacant WBC Silver title. Khan was too fast and too disciplined for Collazo, flooring him in the fourth round and twice in the tenth. The judges scored the fight 119–104, and 117–106 twice in Khan's favour. Khan and Collazo both incurred point deductions in round eight. Collazo hit Khan with a low blow while Khan was holding his head down. Collazo's failed approach resulted in a mismatch on the scorecards. Collazo fought with his hands down most of the night, unafraid of Khan, believing Khan had no power and he would eventually knock him out. In the post-fight interview in the ring, Khan credited his twelve months of boxing training with Virgil Hunter for his success. Khan's purse for the fight was $1.5m while Collazo earned $350,000.
