Harry Redknapp will make late a decision on the fitness of Ledley King ahead of Wednesday night's Champions League match against FC Twente.
The skipper and central defender missed Saturday's loss at West Ham after picking up a slight groin problem in training on Friday.
"We're not sure on Ledley but I'll say he's probably doubtful," reported Harry at this afternoon's press conference.
"If he's fit, he'll play, but I'm not sure if he will be fit.
"Charlie (Vedran Corluka) will play at centre-back again if Ledley's not right. I can't see too many changes at the back."
Harry had bad news to report though as Younes Kaboul tweaked his hamstring in training on Tuesday morning.
Meanwhile, the manager said he will make a late decision in goal with Heurelho Gomes fit and training again after picking up a groin injury in the first half against Wigan on August 28.
However, Carlo Cudicini has been in fine form and produced a number of top-class saves at West Ham.
"Carlo has played very well and I'll make that decision tomorrow," added Harry.
Michael Dawson (ankle/knee), Jermain Defoe (ankle) and William Gallas (groin) remain out.
