England have confirmed Morgan Gibbs-White, Ezri Konsa and Kobbie Mainoo have withdrawn from the squad with injuries.
Captain Harry Kane was earlier declared fit after an injury scare.
England interim boss Lee Carsley has elected against drafting in any replacements after the FA confirmed Konsa, Mainoo and Gibbs-White have all withdrawn from international duty due to injury.
"The trio all sustained injuries for their respective clubs over the weekend and have been ruled out of the Three Lions' UEFA Nations League fixtures against Greece and Finland," an FA statement read.
"All other 22 players are at St George's Park with no further additions planned at this time."
Defender Konsa started in England's most recent outing - a 2-0 home win over Finland - while Mainoo played 77 minutes in Carsley's first match in charge - a 2-0 triumph over the Republic of Ireland in Dublin.
The Three Lions host Greece on Thursday before flying to Helsinki to face Finland on Sunday.
