Former MotoGP world champion Nicky Hayden has undergone surgery on the right wrist he injured during the final race of the season in Valencia on 7 November.
The Ducati rider was caught in a four-rider crash at the first corner of the race.
The American, world title winner in 2006, had a screw inserted into his fractured scaphoid bone during surgery in California.
"Everything went pretty smoothly," Hayden said. "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."
