Graveney concedes Vaughan is struggling

David Graveney has admitted that the chances of Michael Vaughan returning to captain the one-day series are very doubtful, and that his tour is "very much in the balance". Vaughan flew home to the UK on Sunday, and today will see a specialist to ascertain the severity of his knee injury.

"Without doubt he's had problems with this knee before," Graveney told the radio programme BBC Today. "The last thing you want is to lose your captain but we'll follow whatever medical advice is recommended."

Vaughan missed the first Test of England's tour of Pakistan after injuring his knee during a warm-up game against a Pakistan A side at Lahore. Although he was passed fit for the remaining two Tests, he was in obvious discomfort while batting and in the field.

"Michael is due to see a specialist later on today about how bad his knee is and I'll touch base with him once he's had that and we'll go from there," Graveney added. "Michael missed the first Test and was understandably pretty down about that but he then made a remarkable recovery from the early prediction so we'll try to be as optimistic as possible.

"I'd obviously love him to go back and I'm sure he wants to go back himself. So let's see how it goes when he sees the specialist today."
