Page "Samuel Serrano" Paragraph 6

Serrano and his corner filed a complaint, however, claiming the cut had been caused by a headbutt instead, and upon review at the WBA's Panama City offices, WBA officials announced they had effectively seen the headbutt that Serrano claimed opened his cut happen.

So the WBA decided the cut had come from a headbutt, and the judges ' scorecards were reviewed.

They had Serrano ahead on points after 10 rounds, so the fight, and the crown, were given back to Serrano by a technical decision.
