PARIS, FRANCE -- A French newspaper reports that follow-up tests on
backup urine samples by Tour de France winner Floyd Landis turned
up traces of synthetic testosterone. The tests on seven "B" samples clearly showed traces of the banned substance, according to the paper L'Equipe. Initial tests on his "A" sample after the 17th stage of the race were positive.

Landis has an arbitration hearing May 14th in California and it
is believed he will question the practices of the French lab that
conducted the tests.

The president of the French anti-doping agency tells the
Associated Press that the tests were completed this weekend but
that he doesn't know the results.
