ZHANGJIAKOU, China (AP) — U.S. Ski & Snowboard is investigating allegations that longtime Olympic coach Peter Foley took naked pictures of female athletes and that Olympic snowboard racer Hagen Kearney used racist language to provoke a teammate.

Both are in China at the Beijing Games this week.

Former snowboardcross rider Callan Chythlook-Sifsof wrote in an Instagram post that Foley had taken naked photos of female athletes and made inappropriate comments.

She also wrote that Kearney repeatedly used the N-word. Foley denied the allegations to The Associated Press.

A message sent to the company representing Kearney was not immediately returned.
