** FILE ** Germany's Jan Ullrich rides his bike to win the silver medal in the Olympics cycling men's individual time trials, in this Sept 30, 2000 file photo, at the cycling road course in of the Summer Olympic Games in Sydney. The IOC opened an investigation Wednesday, May 30, 2007 into possible doping violations in cycling at previous Olympics following recent drug confessions by members of the Telekom team. A flurry of admissions by former Telekom riders last week that they used EPO further damaged cycling's credibility. The International Olympic Committee set up a disciplinary panel "to inquire into possible anti-doping violations at previous Olympic Games, in connection with recent revelations concerning the Telekom Cycling Team." The probe could put further scrutiny on Jan Ullrich, the 1997 Tour de France champion who won the Olympic gold medal in the road race and silver in the time trial at the 2000 Sydney Games.
