PARIS (Reuters) - Tour de France winner Floyd Landis has tested positive for the male sex hormone testosterone, the U.S. rider's Phonak team said on Thursday, dealing a savage blow to cycling's most prestigious race.
"The Phonak Cycling Team was notified yesterday by (world cycling body) the UCI of an unusual level of testosterone/epitestosterone ratio in the test made on Floyd Landis after stage 17 of the Tour de France," Phonak said in a team statement.
If Landis's B sample confirms the result, the 30-year-old American is certain to be stripped of his victory, becoming the first Tour winner to be disqualified for doping.
Spaniard Pedro Delgado tested positive for a masking agent on his way to Tour victory in 1988 but was allowed to continue in the event because the substance was not on UCI's list of banned products then.
If Landis were disqualified, Spain's Oscar Pereiro, who finished second in the overall standings, would be declared the winner.
"Until the UCI confirm it, it isn't possible to say anything, despite what Phonak have said," Pereiro told the Web site of sports daily AS.
"In any case, at the moment I have a bittersweet feeling because it is bad news for cycling, and I would prefer to remain second and that they don't confirm the positive."
INCREDIBLE COMEBACK
In the 17th stage, a grueling ride to Morzine in the French Alps, Landis produced an incredible comeback a day after a disastrous showing had appeared to ruin his chances of victory.
The rider from Pennsylvania crossed the line over five minutes ahead of Spaniard Carlos Sastre and went on to win the race in Paris on Sunday, succeeding compatriot Lance Armstrong who retired last year after winning the Tour a record seven times.
Phonak said Landis would not ride until the matter had been clarified and if the B sample confirmed the positive result, the rider would be dismissed.
"The team management and the rider were both totally surprised by this physiological result," Phonak added.
"The rider will ask in the upcoming days for the counter analysis to prove either that this result has come from a natural process or that this is the result of a mistake," the statement read.
Landis pulled out of races in the last two days without giving any explanation and organizers of those events were unable to contact him.
Dutch news agency ANP quoted his team mate Koos Moerenhout as saying that Landis had pain from a hip problem and had gone to see his doctor in Germany.
The UCI announced on Wednesday a rider had tested positive during this year's race. The ruling body did not name the rider or give further details.
DOPING SCANDAL
This year's Tour was hit by a doping scandal on the eve of the opening prologue.
Giro d'Italia winner Ivan Basso of Italy and Germany's 1997 Tour champion Jan Ullrich were forced to pull out and were suspended after being implicated in a doping investigation in Spain. The pair denied any wrong-doing.
Ullrich was later sacked by his T-Mobile sponsor while team mate Oscar Sevilla and manager Rudy Pevenage were suspended.
The Astana-Wuerth team had to withdraw as five of their riders were on a list of nine Tour competitors provided by Spanish police in the biggest doping scandal since the Festina affair which rocked the 1998 race.
The investigation came to light in May when the Spanish Civil Guard raided addresses in Madrid and Zaragoza and found large quantities of anabolic steroids, equipment used for blood transfusions and more than 100 bags of frozen blood.
A notoriously tough sport, cycling has been plagued by doping for years.
Landis's win had been welcomed by observers, who said it lifted some of the gloom hanging over the event after its traumatic start.
Asked if he had a message to deliver about doping after his victory, Landis had said: "In this sport, we proved that more than any sport we try to prevent doping and try to solve the problem.
However, he added: "Cycling has a reputation that doesn't seem to want to go away."
