Everton’s Alex Iwobi is expected to be out for three weeks after damaging ankle ligaments during Friday’s defeat by Manchester United.
The Toffees lost the FA Cup third round tie 3-1 at Old Trafford.
The midfielder left the field on a stretcher during the second half after a tackle by United’s Tyrell Malacia.
The injury is a further blow to Everton, who dropped into the Premier League relegation zone after a heavy home defeat by Brighton last week.
Defender Conor Coady conceded they are in “a bad place” but they have showed they are fighting for under-pressure manager Frank Lampard.
