Tour de France champion Floyd Landis got more bad news Monday – a report that follow-up tests on his backup urine samples found traces of synthetic testosterone.

But he refused to confirm the results and said the report on the Web site of French newspaper L’Equipe was yet another result of unethical maneuvers engineered by those who want him stripped of the Tour title.

“In any other industry or field, their failures would be construed as criminal negligence,” Landis said during a teleconference Monday.

Landis’ attorney, Maurice Suh, said he has received some documentation from the tests done on the “B” samples at a lab outside of Paris, but it was not complete.

During the 2006 Tour, Landis tested positive for elevated testosterone to epitestosterone levels after he won the 17th stage. The 31-year-old cyclist, who repeatedly has denied doping, faces the loss of his title and a two-year ban if an arbitration panel upholds the positive test.

Landis faces becoming the first rider in the 104-year history of the Tour to be stripped of the title.
