Everton are considering their options after Dominic Calvert-Lewin picked up an injury just days before the start of the new season.
The forward missed training today after picking up a knock in yesterday's session.
It's unknown how severe the injury to Calvert-Lewin is, but with Everton hosting Chelsea on Saturday he could miss the season opener.
Toffees boss Frank Lampard now faces the prospect of going into the game without a striker.
