Tottenham boss Harry Redknapp admits Scott Parker could miss Euro 2012 if his Achilles fails to respond to treatment.
Parker has had an injection on his injured Achilles which forced him to miss last weekend's win over Fulham.
New England boss Roy Hodgson is set to name his squad for the finals in Ukraine and Poland on Wednesday and Parker, who captained England last time out against Holland, is now a major doubt.
Redknapp hopes Parker can recover in time to take his place in the squad with the club's medical staff confident the injury will settle down.
"He has had an injection and hopefully that will do the trick," Redknapp told Sky Sports News. "It should settle it down, it might be seven or eight days and then he could be okay to start training again and playing.
"I just hope he is going to be okay for the Euros for his sake and for England as well.
"If the injection doesn't work then obviously he has got a problem, we will have to see where we go from there and see if something more drastic is done.
"I think they [the medical team] are quite confident the injection could do the trick, so let's hope so."
Redknapp believes Parker could be one of four players in Hodgson's squad for the finals alongside Jermain Defoe, Kyle Walker and Aaron Lennon.
"Yeah I am sure they have got a chance - Aaron, Jermain, Kyle Walker and Scott - so I wouldn't be surprised if four of them made it but i wouldn't be sure."
