Liverpool will be without captain Steven Gerrard and striker Fernando Torres for their Europa League play-off second leg against Trabzonspor in Turkey on Thursday.
Gerrard has a back problem while manager Roy Hodgson has decided not to risk Torres in a third successive game following his injury problems last season.
However, both are expected to be fit for Sunday's Barclays Premier League clash with West Brom.
Defender Daniel Agger (concussion) and Maxi Rodriguez (illness) are also missing from the squad which travels to Turkey on Wednesday morning with a 1-0 lead from the first leg.
"Steven Gerrard unfortunately has had a recurrence of the back problem which he gets from time to time," said Hodgson.
"Hopefully it won't stop him playing on Sunday.
"With Fernando Torres we've made the decision that we don't wish to risk him three games in a row at this stage of the season with him having done so well to get back this quickly.
"Agger played in the game on Monday (the 3-0 defeat to Manchester City) which was to some extent against medical advice.
"He wanted to play but felt a bit sick after the game. That's mainly due to the concussion he suffered (against Arsenal), so it would be foolish for us to risk him.
"Maxi is sick. He's in bed at the moment with a bit of gastroenteritis, so he's out of the question."
