MAROUANE FELLAINI was still on crutches today as Everton waited for confirmation of the extent of the midfielder's ankle injury.
David Moyes revealed on Saturday that his record signing had not sustained any fracture in the challenge which saw Sotirios Kyrgiakos sent off in the Anfield derby on Saturday afternoon.
But the Blues will not know the extent of any further damage until the swelling has gone down.
Fellaini will definitely miss tomorrow night's visit of Chelsea and could be sidelined for several weeks if he has sustained any ligament damage.
If the Belgian is ruled out for any significant period of time it would represent a major blow, as he was enjoying the best form of his Everton career so far.
Everton have already suffered major injury blows in the past 12 months with successive players of the year Phil Jagielka and Mikel Arteta both suffering cruciate knee ligament injuries.
Sylvain Distin, meanwhile, insists the best way for Everton to overcome their derby disappointment is to bounce back against Chelsea.
The French defender admits there was a sombre atmosphere in the away dressing room following Saturday's 1-0 defeat at Anfield, but says there is no time for anyone to feel sorry for themselves.
Premier League leaders Chelsea arrive at Goodison Park tomorrow night.
