LAUSANNE, Switzerland (AP) - The director of Switzerland's anti-doping lab has disputed claims by U.S. Anti-Doping Agency CEO Travis Tygart that he helped Lance Armstrong avoid being caught for doping.

Lab director Martial Saugy called a news conference Friday to challenge accusations that he provided Armstrong with information on how to avoid detection for use of EPO.

Tygart told the television program "60 Minutes Sports" on Wednesday that Saugy acknowledged to him that he gave Armstrong and team manager Johan Bruyneel, "the keys to beating EPO tests" before the 2002 Tour de France.

Saugy says he and Tygart have "different memories" of their discussion in 2010 soon after U.S. federal investigators opened a probe into Armstrong.

Saugy repeated his claim that his 2002 meeting with Armstrong was ordered by international cycling federation UCI. He denies it was wrong to meet with the rider.
