A "monumental cloud" will hang over Spanish sport until all the athletes involved in the Operation Puerto case are identified, according to the head of the World Anti-Doping Agency (WADA).

There were some snafus but overall it was a great event.

The International Cycling Union (UCI) did all it could to stall its doping investigation into Lance Armstrong, U.S. Anti-Doping Agency chief executive Travis Tygart said Wednesday.

Luxembourg's anti-doping authorities suspended cyclist Frank Schleck until July 14 after he tested positive for a banned substance during last year's Tour de France.

The World Anti-Doping Agency called the UCI "deceitful" Tuesday for shutting down its independent doping panel and said it won't participate in an amnesty commission set up by the cycling governing body.

The International Cycling Union (UCI) disbanded what is claimed was an independent commission put together to review any involvement the cycling governing body had in the Lance Armstrong scandal, saying it will go ahead with a "truth and reconciliation commission" instead.

The first public hearing into the Lance Armstrong doping scandal descended into sharp exchanges in London on Friday over the lack of disclosure of documents by the sport's governing body.

Just days after Lance Armstrong's doping admission, professional cycling is set for more damaging revelations when the long-delayed Operation Puerto case finally goes to court in Spain.

The World Anti-Doping Agency (WADA) disputes a claim by former international cycling union (UCI) president and current honorary president Hein Verbruggen that discussing suspicious doping samples with athletes was the normal practice in sports.

UCI Honorary President Hein Verbruggen says the International Cycling Union (UCI) held meetings with riders, including Lance Armstrong, to warn them when suspicious test values showed they were coming close to testing positive for performance enhancing drugs.
