Collecchio - Australian rider Michael Matthews has pulled out of the Tour of Italy before Wednesday's 11th stage, his Orica team announced.
The 23-year-old, who wore the leader's pink jersey for six days, suffered a right thigh injury in a fall on Sunday.
Despite that misfortune Matthews, who won the sixth stage, went on to take third in Tuesday's 10th stage.
"Michael fought to get a result despite the pain," Orica said.
"What's certain is he's learnt a lot from this Giro."
