The World Anti-Doping Agency (WADA) have joined the International Cycling Union (UCI) in appealing against the acquittal of three-time Tour de France winner Alberto Contador following a positive test for a banned substance.

THE saga over Alberto Contador’s positive test for clenbuterol is set to rumble on after the International Cycling Union (UCI) yesterday confirmed they would take the case to the Court of Arbitration for Sport (CAS).

The International Cycling Union (UCI) have confirmed they will appeal against the Spanish cycling federation's decision to acquit Alberto Contador after the three-time Tour de France winner tested positive for the banned substance clenbuterol last year.

THREE-TIME Tour de France champion Alberto Contador is set to line up in the Tour of the Algarve today after the competitions committee of the Spanish Cycling Federation (RFEC) decided to overturn its decision to ban him for a year following his positive test for the banned substance clenbuterol.

Alberto Contador has been cleared by the Royal Spanish Cycling Federation after testing positive for a banned substance during last year’s Tour de France and can return to competition immediately, his spokesman said today.

Alberto Contador has vowed to fight his proposed one-year doping ban, saying: “I will appeal in every possible court to defend my innocence”.
