Everton boss David Moyes has revealed Darron Gibson is set to be sidelined for a month.
The Republic of Ireland international missed Sunday's 2-1 home defeat by Chelsea after picking up a thigh injury.
Gibson, 25, only returned to action in November after around three months out with a similar problem but is now facing another lengthy spell on the sidelines.
"I think he's going to be out for about four weeks," said Moyes.
