Mark Cavendish was injured in today's tenth stage of the Tour de France, from Pau to Hautacam.
He collided with American rider Danny Pate early on and needed medical treatment for an injury to his left shoulder.
Mark carried on, finishing 169th, and is now two hours behind race leader Cadel Evans from Australia.
It's not known whether he intends to continue after today's mishap.
Stage ten was contested over 156 kilometres, and was won by Leonardo Piepoli.
On Saturday Mark Cavendish became only the second British cyclist ever to win two stages of the Tour de France in the same year.
