The 25-year-old Killybegs man is now also a doubt for next Tuesday’s European championship game against World champions Germany, though Martin O’Neill has named him in his squad.
Coleman has missed five games since picking up a head injury in a Europa League triumph over Wolfsburg.
It subsequently emerged that a soft tissue problem with his hamstring is the reason for the 25-year-old’s prolonged absence.
He missed the trip to Man United today when Everton were unlucky not to get a draw.
“Seamus Coleman had concussion against Wolfsburg but then he suffered a little bit of a soft tissue problem. I don’t think it will be too long (before he is fully fit). The international break should clear those injuries,” said Everton manager Roberto Martinez.
Squad: David Forde; Shay Given; Keiren Westwood; Rob Elliot, Richard Keogh; Marc Wilson; Seamus Coleman; John O’Shea; Alex Pearce; Ciaran Clark; Stephen Ward, Hendrick; Whelan; Gibson; McGeady; Walters; Pilkington; McClean; Brady; Quinn; Meyler; Hoolahan, Robbie Keane; Shane Long; Daryl Murphy; Kevin Doyle; Anthony Stokes.
