MotoGP rookie Alvaro Bautista has been taken to the Brno medical centre on a stretcher after an accident halfway through the Saturday morning practice session.

Bautista - who fractured his collarbone on a motocross bike earlier this year, forcing him to miss a race - was 15th fastest at the time of his accident.

The Rizla Suzuki rider was able to wave as he was carried through the doors of the medical centre.

The track was cool and misty this morning and had previously caught out Randy de Puniet, who is returning to action just one month after breaking his leg.

The LCR Honda rider was fortunately able to limp away from the accident without assistance.
