Everton’s Ben Godfrey and Tom Davies have failed late fitness tests ahead of the U21 European Championship group stage match between England and Croatia.
Both Godfrey and Davies have impressed with the Toffees this season.
Godfrey signed for Everton from Norwich City last summer in a big-money move and has lived up to expectations with several impressive performances.
Davies has also shown signs of improvement during the campaign, despite not playing a full 90 minutes since the Merseyside derby.
Both players were expected to be included in the matchday squad on Monday evening when Everton face Crystal Palace, but their involvement has now been thrown into doubt.
