Chaz Davies has been forced to withdraw from the opening round of the 2012 World Superbike Championship after suffering a suspected broken wrist in an accident during Q2.

The reigning World Supersport Champion had been due to make his WSBK debut at Phillip Island this weekend, but a fall from his ParkinGO MTC Aprilia in the closing minutes of Q2 has now forced him onto the sidelines.

The latest rider to suffer an injury at Phillip Island, following similar woes for Leon Haslam, Eugene Laverty, John Hopkins and David Salom, Davies's disappointment comes after he had done enough to qualify for Superpole prior to the accident, the Welshman having managed 15th quickest.

As well as a bitter blow for Davies, who now has a month to recover before the second round at Imola, his injury will also delay ParkinGO's long-awaited WSBK debut.
