The England international has failed to hold down a regular place in the Reds engine room this term, with niggling injuries hampering him of late, but their recent dip in form prompted calls for his return to the team.
Murphy turned out for Liverpool's reserves against local rivals Everton on Monday in the hope of proving his fitness and form to Reds chief Gerard Houllier.
However a challenge by Kevin Campbell on 42 minutes ended Murphy's participation in the game, with the club initially forecasting a month out of action for the midfield schemer.
Murphy will undergo scans on Tuesday, but Liverpool believe he has suffered ligament damage in his ankle.
As well as missing Liverpool's upcoming games at home and in Europe, Murphy will not now figure for England in their pivotal Euro 2004 encounter with Turkey.
