Liverpool expect to discover the results of the treatment Steven Gerrard had on an ankle infection over the weekend within the next couple of days but are keeping an open mind over the extent of the problem.
The Reds captain missed Saturday's 2-0 win at West Brom as, after initially travelling to the midlands on Friday with the rest of the squad, he was not fit enough to play in the evening kick-off the following day. Gerrard is believed to have picked up a knock in training which subsequently became infected and required medical intervention at a Liverpool hospital on Sunday.

The club will not comment on Gerrard's fitness but Press Association Sport understands there will be no prognosis on the problem or definitive decision on what treatment he will undergo until at least Tuesday.
Any time on the sidelines would be a blow to Gerrard and Liverpool as the player has only just returned to action after six months out. Gerrard had an operation on a long-term groin problem in March and his comeback from that was delayed by a because of an infection.
He finally made his return in the second half of Liverpool's Carling Cup victory at Brighton on September 21 and, after two further substitute appearances, started his first match since March 6 in the draw with Manchester United just over a fortnight ago.
His latest injury set-back, however, could put his participation in England's friendlies against Spain and Sweden on November 12 and 15 at Wembley in doubt.
He missed this month's final Euro 2012 qualifier in Montenegro as he had played less than an hour's football in the current season and so was not selected by England coach Fabio Capello.
The coming international break could give him time to recover for a tough spell for his club towards the end of the month when they travel to Chelsea twice - once in the Carling Cup quarter-final - and host Barclays Premier League leaders Manchester City.
But Dalglish, as he said at the weekend, will not know for a day or two.
"Will he be fit for England? I haven't got a clue," he said at The Hawthorns. "It's nothing to do with any injuries before, it's an infection. We will be back in Monday or Tuesday so we can be more accurate."
