By Hedwig Kröner in Briançon
The wearer of the Green jersey might not be able to take the start of stage 12. Tom Boonen crashed on the very first descent of today's race to Briançon after only 12 kilometres. He injured his right knee, but was able to continue and finish today's stage within the time limit. Later during the evening, his knee was reported to be seriously swollen, endangering his departure to Digne-les-Bains tomorrow.
