Casey Stoner has been diagnosed with a torn ligament in his right ankle following his Indianapolis MotoGP qualifying crash.
The Honda rider was taken for x-rays at the circuit medical centre as the initial suspicion was that he had sustained a fracture in the accident, but it was subsequently confirmed that damage was limited to the ligaments following the x-ray and an MRI scan.
Stoner had been on provisional pole when he had the violent high-side at Turn 13 early in the qualifying session, flying through the air and landing heavily on his feet before rolling through the gravel.
The crash was the first of three similar accidents at the same spot, with Americans Ben Spies and Nicky Hayden also suffering high-sides. Spies had a violent landing on his back but was able to rejoin later in the session. Hayden was unable to get up after his crash and was taken away by ambulance, although he was conscious and waving to the crowd as he was stretchered away.
