Same thing happened to a Spanish cyclist who got suspended for 2 years after a juridical battle.
But he tested positive after the injury. Before the injury they did testing aswell and he passed flying colors. And he did test positive for some kind of substance that supposedly stayed in the body for a long time and it was a dumb thing to use.
* I used to think that it was contamination because he did not test positive before but now i realized that they might have messed up the "masking"
