Ducati MotoGP star Nicky Hayden has undergone minor surgery on his right wrist.

With Ducati not attending next week's private test at the new Austin circuit, the American has taken advantage of the break before the final official test at Jerez on March 23-25.

"Minor tune up last night to clean up some old scar tissue. All went smooth just a small set back," Hayden wrote on his official Twitter page, @NickyHayden.

Repsol Honda, LCR Honda and the Factory Yamaha teams will be at Austin next week.
