Schumacher appeals to CAS

German cyclist Stefan Schumacher has initiated proceedings before the Court of Arbitration for Sport (CAS) in Lausanne, Switzerland, to overturn his suspension from competition resulting from testing positive in last year's Tour de France.

"He made his request to us on April 1," said a representative of CAS, as reported by AFP.

In February, the French anti-doping agency (AFLD) suspended the 27-year-old Schumacher for two years after testing positive for CERA, a new generation of EPO, during the Tour de France.

The International Cycling Union UCI then confirmed the AFLD's two-year ban against Schumacher which expanded his race ban from French soil to all UCI races world-wide.
