AIGLE, Switzerland (AP) - Olympic bronze medalist and three-time world time trial champion Michael Rogers of Australia has tested positive for clenbuterol.
The International Cycling Union says Rogers is provisionally suspended while his national federation investigates the case.
The UCI says Rogers tested positive for clenbuterol at the Japan Cap on Oct. 20.
Clenbuterol, which helps build muscle and burn fat, is the substance Alberto Contador tested positive for at the 2010 Tour de France.
Rogers joined Contador at Team Saxo-Tinkoff last season from Team Sky, where he rode in support of 2012 Tour winner Bradley Wiggins.
Rogers left Sky after being named in evidence in the Lance Armstrong case as working with the American's doctor Michele Ferrari.
Rogers was upgraded to bronze in the time trial at the 2004 Olympics when Tyler Hamilton was disqualified.
