Alessandro Petacchi has had to withdraw from the Tour of Spain and will miss the rest of the season after punching his team bus at the end of stage 15.
Petacchi missed the 2006 Tour of France after crashing in the Giro d'Italia
The Milram rider lashed out after failing to win Sunday's stage and broke a bone in his hand.
"I know I've done something stupid but I did it because I was very angry after having a real chance of winning for the first time for months," he said.
"There's no doubt I've made a mistake but I'm a human being, not a machine."
Petacchi fractured his kneecap during stage three of the Giro d'Italia in May and subsequently missed the Tour de France in July.
