Simon Cho one of America's biggest ice-skating stars has been banned for two years after tampering with a rival's skates.

Cho's suspension lasts until October 2014, so he will miss the Winter Olympics in Sochi, Russia.

After denying wrongdoing, Cho said in October his coach told him to sabotage Canadian Olivier Jean's skates during the 2011 World Team Championship.

News of Cho's suspension came on the day the US team for the short track event was announced, ahead of the World Cup Championship.
