If this is correct, the whole Tour de France blows up.
I hope this isn't true but he WAS on the same team as Tyler Hamilton, whom Phonak kicked off after he tested positive for blood doping at the Vuelta. This is truly horrible news, if true, for his family and for US bicycling. If he did test positive, I can only hope it was due to some drug he took for his hip.
I thought it already did when all those riders bailed early on due to drug testing?
