Liverpool have admitted that the groin injury sustained by captain Steven Gerrard is somewhat of an unknown quantity.
The England midfielder had an operation on his groin in early March and was set to return to action last weekend against West Bromwich Albion but tweaked something at training and is now set to spend the rest of the season on the sidelines.
Reds boss Kenny Dalglish said that the problem was something they aren't quite aware of just yet and also said that those not available for selection are basically redundant and should not be focused on.
"We still don't know definitively what the problem is," said Dalglish.
"We will wait to get a precise answer from the people that he has to see but he won't be involved again this season.
"It is a blow to anyone but it's more disappointing for the players than it is for us, obviously.
"We just have to get on with it and without being disrespectful to the players who are injured the most important ones are the ones who are fit.
"They are the ones who can be chosen. At this particular moment in time I'm as good a player as Steven."
