Tom Huddlestone was carried off on a stretcher after getting his foot caught by John Heitinga while taking a shot during the 2-1 win at White Hart Lane, adding to Redknapp's problems in central midfield as Jermaine Jenas requires surgery this week on a groin injury and Wilson Palacios is walking a disciplinary tightrope on nine bookings.
In defence, Ledley King has a thigh problem and Jonathan Woodgate looks likely to miss the rest of the season with his long-term groin complaint.
The news from the specialist treating Aaron Lennon is that the England winger needs at least six weeks' rest, with David Bentley unable to deputise as he has a tear in his groin.
"Tom will have a scan and we'll see how it is," said Spurs boss Redknapp. "I don't know how bad his injury is, it doesn't look all that good at the moment. But we are running out of central-midfield players. We've only got three anyway, we've got Palacios, Tom and Jermaine Jenas.
"Jenas looks like having an operation on Wednesday probably, we don't know how Tom is and Wilson's on nine bookings so it's not an ideal situation. It's an area we've been light on all year really."
