SOCHI, Feb. 23 (Xinhua) -- The Canada Freestyle Ski Association (CFSA) and the Canadian and Slovenian Olympic Committees are seeking the disqualification of French medalists Jean Frederic Chapuis, Arnaud Bovolenta and Jonathan Midol from the men's ski cross held on Thursday.

CFSA, Canada and Slovenia allege that, shortly before the big final, French support staff changed the shaping of the lower leg suits of their skiers, creating an unfair aerodynamic advantage.

The Court of the Arbitration for Sport (CAS) is expected to announce the decision by 14:00 on Sunday.

Both Canada and Slovenia had earlier protested the result to the world skiing governing body FIS, which ruled the protests had not been filed on time.
