Everton are still to discover the full extent of goalkeeper Tim Howard's injury suffered while on international duty with the United States.
Howard has been impressive for Everton this season
The Everton goalkeeper dislocated his finger in the 4-2 defeat by Brazil.
"Tim has injured his finger and we don't know much about it," head physio Mick Rathbone told evertonTV.
"Obviously with the time differences and everything we're collating all the information. We are expecting further information."
With Howard impressive in goal, Everton have made a promising start to the season and are currently third in the table.
David Moyes' side have the same number of points as leaders Liverpool, though Everton have played one more game.
