Meanwhile Italian rider Luca Wackermann has been released from hospital following a crash at the Giro d'Italia and will return home, his team said on Thursday.
The crash, which brought down Wackermann and Dutchman Etienne van Empel, happened at the end of Tuesday's fourth stage when a barrier was blown over by the draft from a low-flying helicopter and struck the two riders. Wackermann, 28, suffered concussion as well as a fracture of the nasal bones and multiple contusions. He also had bruises to his arms and legs and a suspected back fracture and was forced to withdraw from the race.
