The team confirmed today that Casar has sustained a fracture to the scaphoid bone in his wrist, and will not start tomorrow morning. He will be in plaster for three weeks to allow the break to heal.
A professional since 1999, Casar has already competed in 17 Grand Tours: 11 Tours de France, four Giri d'Italia and two Vueltas a Espana.
His last Grand Tour stage win came in the 2010 Tour de France when he beat Luis Leon Sanchez and Damiano Cunego from a breakaway into Saint-Jean-de-Maurienne on stage 9.
He has three Tour de France stages to his name, but has never won a stage in the Giro.
