Liverpool midfielder Joe Cole could miss next Sunday's clash against former club Chelsea with a hamstring injury.
The 28-year-old, who moved to Anfield on a free transfer in the summer, limped out of Sunday's Barclays Premier League win at Bolton just after the hour. The club do not feel the problem is serious but his ability to train this week is likely to be affected.
Manager Roy Hodgson said: "He has a slight hamstring injury and we don't know the extent of it until after he has a scan."
Without him Liverpool went on to win 1-0 courtesy of a late Maxi Rodriguez strike.
The experience is a new one to Cole having never suffered such a muscle injury in his career. Having already served a three-match ban this season, it is also another setback as he attempts to establish himself at Anfield.
The Reds could be boosted for the visit of the champions and league leaders by the return of Dirk Kuyt.
The Dutchman has made a rapid recovery from an ankle injury sustained on international duty earlier this month.
Hodgson said: "I think he will be available to be in the squad against Chelsea, but whether he is fit enough to play remains to be seen.
"I think he will return to training towards the latter part of the week and then it is a question of seeing how well he can cope."
Another former Chelsea player, Glen Johnson, is also expected to be available after a thigh strain.
