If the presence of the plasticizer is confirmed he's done...
That said it's really depressing to see professional cycling tearing itself apart like this repeatedly...

Football season has just started here and you can't tell me the pro ranks aren't riddled with steroid users and yet you don't see headlines when somebody trips up and tests positive. They don't strip a Super Bowl win from a team if a player tests positive after the fact......not apologizing for Contador or any other rider but in the end the sport is being marginalized. You can't trust race results to hold up over time....they're now saving/freezing urine samples so they can be tested years after the fact when better tests are developed. Is that really what we want ? Do we really want to go back and re-write the final results of races 5, 8, 15 years ago ???
