The prolific England batsman had a precautionary scan on his right knee on Wednesday following the bone bruising injury that occurred in February.
After going through a precautionary scan on his right knee on Wednesday, England's prolific batsman Kevin Pietersen is available for selection for the fifth and final Ashes Test starting at The Oval on August 21, the England and Wales Cricket Board (ECB) said in a statement.
"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," the ECB said in a statement on Wednesday.
"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."
Pietersen, 33, couldn't complete England's tour to New Zealand after injuring his knee and also missed the two-match return series. He also missed the Champions Trophy but recovered in time to face the Australians in the five-match Ashes series. England have an unassailable 3-0 lead after four matches.
