Marlboro Ducati's Nicky Hayden underwent surgery yesterday to put a screw in the scaphoid he broke in the first-corner crash at Valencia last weekend but the right radius bone has been left untreated so far.

Hayden thought he had got away unscathed from the crash but a subsequent scan revealed the scaphoid and radius damage. He flew to California yesterday for a meeting with the legendary Dr Ting and was immediately operated upon. After wearing a brace and using a bone stimulator for four weeks, Hayden will have his wrist X-rayed again to assess its status. He is confident of full fitness for the Sepang test at the end of January,

“Everything went pretty smoothly. The scaphoid is a slow-healing bone, so you don’t want to wait, only to find out in January that it’s not healing correctly. I’m happy to get it fixed right so that I’ll be ready to go when I need to be," said Hayden.
