First a favored Khazak rider gets nailed for a banned blood transfusion or such just before kicking ass in a time trial, then some other schlub I've never heard of before gets led away from the finish in handcuffs. And now the race leader got tossed by his team after it turned out he was lying about vacationing in Mexico in June, while someone caught him training in Italy (and doing who knows what else).
At least the American contender appears to be clean. For now.
