Injury scare for O'Rourke

Derval O'Rourke's final preparations for next month's Olympics in Beijing have been hampered by a groin injury, which forced her out of yesterday's 100 metres hurdles at the Aviva London Grand Prix.

O'Rourke retained her national title in Santry last Sunday but a groin problem surfaced in the subsequent days and despite intensive treatment, she had to withdraw from the Crystal Palace meet.
