Following the fight, Khan split from his trainer Oliver Harrison, the trainer for all of his previous 17 professional contests. The break-up was blamed on Harrison's concerns that Khan's public engagements were interfering with his fight preparations. Dean Powell, who has trained former world champions Duke McKenzie and Lloyd Honeyghan, worked with Khan until a decision on a permanent trainer was made. In the same month, Khan had a training session in Las Vegas with Roger Mayweather, trainer and uncle of Floyd Mayweather, Jr.
