Harry Redknapp rates Rafa van der Vaart's chances as '50-50, at best' to face Liverpool on Sunday.
The Dutch playmaker picked up an injury just above his anke in Saturday's 3-2 win against Arsenal and that ruled him out of Wednesday's Champions League victory over Werder Bremen.
Jermaine Jenas is Harry's other main doubt after limping off early against Werder Bremen with a calf problem.
"Rafa's chances are 50-50, at best," reported Harry on Friday morning (November 26).
"He's not going to train with us today, so tomorow is really the last chance for him to be fit.
"We did okay though on Wednesday night, played with two strikers and always looked dangerous.
"Jermain Defoe is also getting fit and he will be involved again. If Rafa's fit, great, but he's doubtful.
"JJ has a tight calf and he's going for a scan today. We're all hoping it's not a tear, we'll have to wait and see on that one."
Good news sees Michael Dawson return to full training with the first team this morning.
Ledley King (groin) remains out alongside longer-term injuries Jonathan Woodgate (groin) and Jamie O'Hara (back).
