Everton defender Leighton Baines faces a longer spell on the sidelines after his hamstring injury was found to be worse than first feared.
Baines picked up the injury during Everton's 3-0 win over Fulham last weekend and was forced to limp off.
It was initially thought the injury would only sideline Baines for two weeks, but scans have shown he could be out of action for up to six weeks.
Toffees boss David Moyes admitted it was a major blow to lose Baines as he is already without Alan Stubbs in defence.
"We have had the results of the scan and it looks like Leighton is going to be out for between four to six weeks," Moyes told the Liverpool Echo.
Blow"It's a blow because he has done so well for us. With Alan Stubbs also out, we are a little bit limited at the back.
"We have been really pleased with Bainesy and he had looked sharp against Fulham, but this is something that happens.
"He had a bad ankle knock against Derby and before that had been in really good form."
