Tour de France winner Floyd Landis has denied cheating after his Phonak team confirmed he has tested positive for excess levels of testosterone during this year's event.
In an interview with an American website, Landis insisted he was innocent of injecting testosterone or using a testosterone patch.
Asked directly if he had cheated, Landis said: "No, come on, man."
The Phonak team announced yestderday that an A sample from Landis, taken after he won stage 17 of the tour by almost six minutes, found an "unusual" level of testosterone/epitestosterone.
The 30-year-old, who is due to have hip replacement surgery in the coming weeks, suggested the cortisone shots he has been taking may have had an effect.
