Britain's Leon Camier has been forced to withdraw from the Phillip Island WorldSBK weekend as his shoulder has not held up well to the demands of the Australian track.

It was always going to be difficult for Camier as the offending joint is still not healed from the pre-season testing crash at Aragon.

The Andorra resident sat out the wet first practice, did 13 laps in the second session and reported after that the shoulder was in bad shape. He didn't go out in free practice three and called it a day before Superpole.

"I'm really disappointed not to be able to race and I want to apologise to all the team. I did everything I could to be ready for this weekend but it was not enough," said Camier.

"I will keep working to be strong in the next race but it's a weekly evaluation process. It was a hard decision, but for now we decided not to race was best."
