Liverpool are preparing themselves for bad news over a possible recurrence of Steven Gerrard's groin injury.
The inspirational skipper was subdued during Wednesday's 3-1 Champions League quarter-final first leg defeat to Chelsea at Anfield.
He was also substituted towards the end of the previous weekend's Premier League victory at Fulham with an ankle problem.
Gerrard underwent a series of medical tests on Thursday at the club's Melwood training complex with reports suggesting he is set to miss the next three games with a recurrence of a groin problem.
The England midfielder has been troubled by a series of groin and hamstring niggles during the course of the season.
Speaking after the Chelsea defeat, Reds boss Rafael Benitez suggested his skipper was struggling with an injury.
He said: "Steven was not 100 per cent - you could see that. It was the same for Fernando Torres, you could see that they were a little tired, not as sharp as before.
"But they have been playing well and we felt it was okay to use them both in this game. We needed them.
"But credit to Chelsea, they were always controlling Steven and making it difficult for him to play. He was not as mobile as normal.
"The injury he had on Saturday was not the problem, his ankle was okay. But we do not know how he is, we will see tomorrow."
