Portsmouth goalkeeper David James' new injury problem is not too serious according to Pompey boss Paul Hart.

The 39-year old England international strained his calf in the warm-up prior to the clash with Stoke City at Britannia Stadium which Portsmouth lost 1-0 but Hart has allayed any fears that it is a threatening problem and it will in no way jeopardise his World Cup chances, despite the fact he is still battling ongoing knee issues.

"He pulled a calf muscle warming up," he said. "The World Cup is in June, a calf muscle is usually about three weeks. I think he will be fit for the World Cup.

"We are managing the situation (regarding James' knee) at the moment and up until now he has been out on the pitch.

"He has to do some gym work to help him through it but he has been there and it has not been a real problem."
