Jakob Piil has been one of the most prominent riders in the Tour so far, but a knee injury has brougPICTURE BY TIM DE WAELE One of this year's most aggressive riders in the Tour, Danish rider Jakob Piil, won't be at the start line on Tuesday's stage in Valras. On the second rest day the CSC rider had to accept that the Tour is over for him because of a knee injury sustained on Saturday's stage to Plateau de Beille, writes Susanne Horsdal. "I made the decision this morning. The situation hasn't improved overnight, and today it's actually harder for me to just walk than it was yesterday. I dare not think what it would be like to sit on the bike," said Piil, who rode most of the first week of the Tour in different breakaways but had to settle for second place behind Stuart O'Grady on the fifth stage as his best result. For team-mate Bobby Julich, who injured his hand in a crash on the same stage as Piil, things were looking a little brighter on the rest day, whereas Carlos Sastre is suffering with severe pain in his back. "At the moment we're more like a camp hospital that a cycling team," writes Jens Voigt in his column on Sport1.de. It is certainly not an optimal situation for Team CSC and their ambition to keep Ivan Basso on the podium ahead of the Alps.
