Team Sky's Mark Cavendish crashed during the sixth and final stage of the Tour of Qatar.
The world road race champion, winner of two stages in the race, went down after a clash of wheels with Tyler Farrar approaching the sprint finish in Doha.
Cavendish, suffering from cuts and bruises, completed the stage without his helmet, but signed autographs before cycling back to the team hotel.
Frenchman Arnaud Demare won the 120km stage and Belgian Tom Boonen the Tour.
Team Sky sports director Steven de Jongh said: "It's a pity to finish the race that way but luckily we have two wins and he has nothing broken, so we can move on to Oman now.
"[Cavendish] wanted to go but [Roger] Kluge came across and he hesitated a bit. He wanted to go again but then they touched wheels with Farrar and went down."
Boonen finished 28 seconds ahead of American Farrar in the overall standings to record his fourth victory in this event.
Juan Antonio Flecha, Cavendish's Team Sky colleague, was a further five seconds adrift in third. Cavendish finished sixth overall.
