The fourth stage of the Tour of Qatar came to a quick end for Robert Wagner of Team Skil-Shimano. The German crashed on a traffic circle within the first kilometre of the day while still in the neutralised zone.
"I crashed before the start, at kilometre zero and I broke the radius bone," said Wagner. "I am waiting for a Qatar doctor to give me the okay so I can fly home."
The 25-year-old German expected his wrist to require surgery, and he was not sure how long he would be out of racing.
