Olympic all-round gymnastics champion Paul Hamm said yesterday that he would return his gold medal if the Court of Arbitration for Sport (CAS) ruled that a judging error denied South Korea's Yang Tae-young the title.

"If it is determined by the rules of gymnastics that I should give back my medal I will," said Hamm, during a teleconference at the end of the 12-hour hearing at a hotel near CAS's Lausanne headquarters.
