Chelsea captain John Terry is undergoing a “precautionary scan” on his right foot after taking a knock in training today.
The news comes as a blow for Chelsea’s preparations as they attempt to win the double when they face Portsmouth in Saturday’s FA Cup final.
If it proves to be a more serious problem, his participation in the World Cup could be in doubt.
A statement from the club said: “John Terry has today taken a knock in training and has gone to hospital for a precautionary scan on his right foot.
“He left Cobham walking freely in a protective boot, and we await the results which are expected on Thursday.”
It also gives England coach Fabio Capello a headache as he prepares for the World Cup in South Africa and the Italian will undoubtedly be monitoring the situation carefully.
