Iannone ruled out of San Marino GP

Ducati MotoGP rider Andrea Iannone has been ruled out of this weekend's San Marino Grand Prix due to injury.

The Italian rider, who won in Austria just under a month ago, crashed at the Turn 13 right-hander just 10 minutes into Friday morning's first practice session at Misano.

Following treatment and initial x-rays at the trackside clinic, he was then taken to Cesena hospital for further checks on his back. Scans then revealed that Iannone is understood to have sustained a micro-fracture to his T3 vertebra.

Ducati will turn to test rider Michele Pirro, who was already running as a wild card for the weekend, alongside Andrea Dovizioso.

Iannone is also considered to be a major doubt for Aragon later this month.
