Double MotoGP world champion Casey Stoner has undergone successful surgery on his injured right ankle.
The Australian suffered torn ligaments and fractures to his ankle, tibia and fibula in a practice accident in Indianapolis 12 days ago.
Although the Honda rider went on to finish fourth in that race, he missed last weekend's event in Czech Republic on doctor's advice.
Stoner, who will retire at the end of this season, went under the knife yesterday and Honda says the operation went well.
The injury has ended the 26-year-old's hopes of winning a third consecutive crown prior to his retirement.
