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 (Huddlestone) will have a scan and we'll see how it is," said 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."
Roman Pavlyuchenko netted his sixth goal in four games.
"Pav scores goals, that's five goals in the last two-and-a-quarter games and you can't ask more than that," said Redknapp, who chose not to sell the Russia striker to Lokomotiv Moscow during the January transfer window. "It's good, it gives me a nice problem, I've got good frontmen."
