Giles will undergo surgery in a bid to make a complete recovery before England's tour of India early next year.

"It is confirmed he will have the surgery but we are still trying to organise the flight for him to return home," spokesman Andrew Walpole said.

Giles told a website he hoped to be available for the Indian tour by having the surgery next week.

"It's cutting it fine for India but by getting it done next week hopefully I'll be on that plane," he said.

The England selectors have already named Somerset all-rounder Ian Blackwell for the one-day series in Pakistan as a replacement for Giles.

England captain Michael Vaughan is also due to return home after the third Test for the birth of his second child and will consult specialists about the knee trouble which kept him out of the first Test in Multan.
