More hamstring woe for Everton winger Mirallas
But Everton boss David Moyes indicated the injury might not be as bad as first feared.
Moyes said: "Kevin has had hamstring problems so we have got to hope it is not too bad, but I don't think it is as bad as we first thought it could be.
"You could see how well we played in the opening 15 minutes and he is a really important player for us. He helped string a lot of things together and we missed him after that - we never really got flowing.
