Kevin Pietersen is in contention for the fifth and final Investec Ashes Test, following a scan on his troublesome right knee injury.
Pietersen flew home early from the winter tour of New Zealand after injuring his knee and missed the two-match return series as he recovered.
He also missed the Champions Trophy but was fit to take on the Australians, helping England to an unassailable 3-0 lead after four Tests.
A statement from the England and Wales Cricket Board read: "Kevin Pietersen had a precautionary scan on his right knee today as part of an ongoing monitoring process following the bone bruising injury that occurred in February.
"Kevin remains available for selection for the fifth Investec Ashes Test and will continue to receive treatment on his right knee as part of his rehabilitation programme over the course of remainder of the series and beyond."
The hosts are keen to win the series 4-0, but will not want to take undue risks with any of their key men now that the urn and the series are secure.
Team director Andy Flower had already made it clear Pietersen would not be available to his county Surrey for Saturday's Friends Life t20 finals day at Edgbaston, with the 33-year-old batsman also struggling with a calf problem which made him a doubt for the Old Trafford Test.
Surrey's caretaker coach Alec Stewart accepted the decision not to make Pietersen available for a rare Brown Caps appearance at the weekend but hopes he is at full fitness for the last Test of the summer.
"There are no problems at all and we fully understand," Stewart told Sky Sports News. "It wouldn't be right for Kev to play in t20 finals day - we accept that.
"Hopefully his knee is right for the Test next week."
The results of his latest scan will be assessed before a decision is made over his availability for the game at Surrey's Kia Oval starting on August 21.
England name their squad for the match on Saturday.
