Everton will have to wait and see whether Dominic Calvert-Lewin will be available for Thursday's clash against Newcastle United.
The striker was absent for the Toffees' 1-0 loss to Wolves at Goodison Park yesterday.
Calvert-Lewin, 24, has struggled to build momentum this season due to injuries and made just nine appearances.
Now the England international has picked up an illness and was left out of the match-day squad against Wolves.
Everton sit above the Premier League relegation zone only on goal difference ahead of a crunch encounter with Newcastle.
But Frank Lampard could not say if Calvert-Lewin will be back.
The Blues boss said: "He's not well so we'll see."
