On March 26, 2009 as a result of the controversial stoppage timing, Barrera's promoter, Don King, filed a protest with the British Boxing Board of Control, WBA and WBO on behalf of Barrera, claiming the accidental clash of heads should have resulted in the fight being ruled a no-contest. Under the rules governing the bout, had the fight been stopped prior to the end of the fourth round due to the accidental headbutt, the official ruling would have been no contest, requiring an immediate rematch. Referee Dave Parris, however, waited until midway through the fourth round before asking the ringside physician to inspect the wound.
