Disgraced German cyclist Patrik Sinkewitz intends to appeal a one-year ban for testing positive for testosterone, the German cycling federation (BDR) said on Friday.

Sinkewitz crashed out of the Tour de France in 2007, and days later it was disclosed that he had tested positive for the banned male sex hormone during a test taken in June.

In November the BDR's disciplinary commission banned Sinkewitz, formerly of T-Mobile, for the reduced sentence of one year because of his tell-all confession about doping methods.

Since T-Mobile sacked him as soon as his positive test was announced, on July 17, 2007, his ban is set to end on July 17, 2008. He was also ordered to pay a 40,000-euro fine.
