Liverpool boss Roy Hodgson expects left-back Paul Konchesky to miss the club's fixtures this week due to a hamstring strain.
The former Fulham defender sustained the blow making an innocuous sliding challenge in Saturday's controversial 2-2 draw with Sunderland.
Hodgson is unsure as to the severity of the injury, although he does not think the 29-year-old stopper will require a lengthy spell on the sidelines.
However, Hodgson does believe he will miss Thursday's Europa League clash at Utrecht and their weekend Premier League fixture with newly-promoted Blackpool.
"He's got a hamstring strain," Hodgson told the club's official website.
"I couldn't tell you exactly how bad it is yet.
"I don't think it's extremely bad but I certainly think it would rule him out for Thursday and next Sunday.
"Hopefully it won't be much more problematic."
