Lahore report: England hit form

Vaughan's chances of playing in the first Test are rated only 'slim' after he twisted his right knee against Pakistan A on Monday.

He has had a scan and will have treatment on the knee before a decision is made.

England's chief medical officer Dr Peter Gregory said: "He's got to be a doubt for the first Test."

The injury happened just five days before the opening Test against Pakistan in Multan on Saturday.

Dr Gregory said Vaughan's injury was complicated further because he had had surgery on the same knee in 2002.

The England captain also missed the opening Test against New Zealand 18 months ago when he was hit on the joint in the nets.

"It's still very sore. We will need 24 or 48 hours to see how he pulls up clinically and responds to the treatment, as well as to take into account what we find on those scans," said Gregory.

And he warned Vaughan's tour could be over if he needs more surgery on his knee.

"He has a history of cartilage damage, and it would be very likely this is too," said Gregory.

"If there is a tear it would be pretty bad for him. Usually with tears you would need an operation.

"We have asked for the scan report done last year and will compare both the scans."

In 2004, Vaughan did not tear the cartilage and was able to take his place in the second Test of the series against New Zealand.
