Internal bleeding sidelines Capirossi.

Double 2005 race winner Loris Capirossi will take no further part in this year's Australian Grand Prix following a huge high-speed accident at the 200kmh turn one during the latter stages of this morning's first practice session, run in cool and windy conditions.

Although an initial examination by the Clinica Mobile revealed no broken bones, it was later deemed necessary to take Capirossi to a private hospital in Dandenong, about 70km from the Phillip Island track.

"Loris felt generally okay after the crash, but after a while he felt some pain in his chest, so he was driven to Dandenong," said Ducati MotoGP project manager Livio Suppo. "He underwent a scan that showed he had some internal bleeding in his right lung. He is having that bleeding drained and is expected to stay in hospital for two to three days. We wish him well and hope he gets better very soon.

"It's a real shame for him because we know he was so keen to secure second place in the World Championship. In Loris' absence, Carlos (Checa - second fastest) did a very good job today. It seems that our tyre/bike package works very well here, so it's disappointing for Loris that he won't be able to enjoy that for the rest of the weekend," added the Italian.

Suzuki's Kenny Roberts Jr fell at the same corner just before Capirossi and will also miss the rest of the Australian Grand Prix after breaking his left wrist.
