Ashley Giles has undergone an exploratory operation on his right hip in Vail, Colorado after suffering pain during Warwickshire's pre-season tour of Grenada.

Giles flew to the States to visit his specialist on Tuesday after withdrawing from the MCC match against Sussex at Lord's last week. At the time he said how frustrating it was to be back on the sidelines. "Unfortunately, now I've gone back a couple of steps but fingers crossed it's nothing too serious and we can sort it out and get me back on the pitch really quickly."

After missing the whole of the 2006 season with persistent hip and groin problems he returned to the England fold during the Ashes tour. He played the first two Tests before being omitted at Perth, and then having to fly home to be with his wife who'd been diagnosed with a brain tumour.

The ECB said they would not be releasing any further information at the moment.
