Tottenham midfielder Scott Parker has been hit by a Euros injury scare.
New England manager Roy Hodgson names his 23-man squad for the Euros on Wednesday and all the players selected are heading to Spain the following Monday for a training camp.
Redknapp said: "Scotty's not fit. I had to put him on the bench at Villa last week. He has an Achilles problem which is not getting any worse but is not getting any better, either.
"At the moment he is struggling. It is not a rupture but it is sore and we will have to see whether he is available to play against Fulham.
"After Sunday he will be having some injections and we're hoping that will clear it up. He's been carrying it for a few weeks.
"The specialist thinks he can clear it up but it is going to take another 10 days rest after the end of the season."
