Las Vegas, Nevada - Ryan Burton was allowed a glimpse into the training camp of Devon Alexander, who is preparing for a battle of former champions when he takes on British superstar Amir Khan on December 13th at the MGM Grand in Las Vegas. Khan-Alexander will headline a Showtime televised tripleheader. Alexander is being aggressive in camp. He's wanted the fight with Khan for a very long time. Golden Boy Promotions was planning to match them last year, but Khan decided to sit on the sidelines to purse a fight with Floyd Mayweather Jr. The winner of Khan-Alexander will be a frontrunner to face Mayweather in May 2015.
