MGM Grand, Las Vegas - British star Amir Khan had a brief reunion with his former strength and conditioning coach Alex Ariza. Khan and Ariza used to work together several years ago at Freddie Roach's Wild Card Gym in Hollywood. They had a very hostile falling out and went their separate ways. But during the post-fight press conference to the Mayeather-Maidana rematch, it was all smiles when the two of them saw each other.
