No start for Boonen

Points leader Tom Boonen (Quick Step) was forced to withdraw from the Tour de France before today's start due to a knee injury sustained on yesterday's 11th stage to Briançon. The 24 year-old fell on the descent after the start in Courchevel, hitting the deck for the third time in five days.

Boonen limped in to finish as part of the autobus, 39 minutes and 46 seconds after stage winner Alexandre Vinokourov.
