Tour de France champion Floyd Landis got more bad news yesterday - 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.

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.

"We need to understand fully from the lab what they did before we're comfortable about saying what they declared to be 'adverse,' " Suh said.

During the 2006 Tour, Landis tested positive for elevated testosterone to epitestosterone levels after he won the 17th stage.

Landis, 31, who repeatedly has denied doping, faces the loss of his title and a 2-year ban if an arbitration panel upholds the positive test.

Travis Tygart, general counsel of the U.S. Anti-Doping Agency that is prosecuting the case against Landis, said agency rules prevented him from discussing active cases.

The "B" samples were tested at the behest of USADA, which is trying to bolster evidence for Landis' May 14 arbitration hearing.

The most recent tests used a technique that can distinguish synthetic from natural forms of testosterone.

Landis and his attorneys contend the test results were leaked by USADA or the Chatenay-Malabry lab where the tests were conducted, and the leaks serve as another example of a "win-at-all-costs" strategy anti-doping agencies are using to find the cyclist guilty. *
