Hayden has successful shoulder op
Nicky Hayden has had successful surgery to resolve the shoulder problem that hampered him in pre-season testing at Sepang.
The 40 minute arthroscopic procedure, carried out by Dr Arthur Ting in California, discovered and repaired a tear in the labrum.
If the rider's recovery goes according to plan, Hayden should be able to take part in the next winter test at Sepang, February 28-March 1.
"It's a setback, but all things considered, I'm pretty happy with how things went," Hayden said.
"It's good that it was possible to do everything by 'scope, and the pain's not too bad. The problem should be fixed now, and I look forward to being able to help out the team as soon as possible."
The Ducati rider had fractured his left shoulder in a training accident just after Christmas. At the time, he opted to avoid surgery but struggled to ride during the test.
The American is optimistic that it will not disrupt his 2012 preparations too much.
"Setbacks are a part of life and a part of MotoGP, so we'll deal with it and do everything possible to get back on the bike in good condition as soon as possible," he said.
"Ducati and the team are putting maximum effort into this championship, and that helps me to keep my spirits high and to be confident heading into the season."
