According to his Fan Club site here: http://fanclublarsvdhaar.wix.com/home
after his big crash in Lille yesterday, Lars has been brought to the hospital in Amersfoort by advice of the team doctor. He's now at home with crutches and a pressure bandage from toe to knee. No bike till Monda, then back to the hospital for ultrasound and a new visit to check if it's just a bruise or maybe a tear of a muscle.
I'm really sorry and hope it's nothing serious.
Get well soon Lars!
