The Three Lions were boosted by the confirmation that Harry Kane's injury against Eintracht Frankfurt was not serious, and he would be able to play a part in the October fixtures.

However, the trio did not arrive with the rest of the squad at St. George's Park, and Lee Carsley is not expected to call up any replacements.

Mainoo made his international debut earlier this year and has made 10 appearances for England, with one of those caps coming under Carsley against Ireland, but a knee injury that forced him off for Manchester United against Aston Villa will keep him out.

Konsa was also forced off in the second half of that match, having suffered a hamstring injury in the 0-0 draw.

Gibbs-White, who was handed his senior England debut by the manager last month, also sustained his issue on Sunday, in a 1-1 draw with Chelsea. At under-21 level, the midfielder made 15 appearances under Carsley, with only six players featuring more under him.

England hosts Greece at Wembley on Friday before travelling to Helsinki to face Finland on Monday.
