WBO mini flyweight champion Ivan Calderon (32-0-1, 6 KOs) and challenger Rodel Mayol (25-3-1, 19 KOs) fought to a six round technical draw. The fight was stopped due to a cut from an accidental headbutt in the sixth round. Judges scored the fight 58-56 Calderon, 58-56 Mayol, 57-57. Earlier, an accidental clash of heads in round four opened up a cut on Calderon’s forehead. Two more headbutts in the fifth worsened the cut. In the sixth round the cut reopened from either a punch or another butt (unclear) and doctors advised to stop the fight at 1:50 in the sixth round. Under WBO rules the fight goes to the scorecards (including the sixth round).
