It is touch and go whether Michael Vaughan will be available for the Fifth Test against Australia at The Oval next week.

Vaughan has not played in the Ashes series following a knee operation earlier this summer and has reported that it is sore following his return to first-class cricket with Yorkshire.

He has been playing in the CricInfo Championship game against Leicestershire, in which he has scored 82 and 47. But in Yorkshire's second innings he was hit on the knee which was operated on.

He will not play in tomorrow's Norwich Union League match at Grace Road and will rest for a couple of days before telling the England management of his prospects for the final Test.

Vaughan said: "I'm very sore from the first two days of Championship cricket. I'm struggling to sprint between the wickets. This might be a natural reaction to first-class cricket.

"I will decide shortly what I will do about the England situation. I'll wait to see how it responds to treatment."

Vaughan has not played for England since making his maiden Test hundred against Pakistan at Old Trafford at the start of June.
