Tottenham midfielder Dele Alli and Liverpool striker Danny Ings have been named in England's squad for the first time.
England will face Estonia and Lithuania in their next Euro qualifiers.
Alli was playing League One football last season, but with Jack Wilshere and Jordan Henderson injured, the 19-year-old could find himself representing his country at senior level over the next couple of weeks.
Ryan Bertrand is recalled to the squad in place of Luke Shaw, who broke his leg in two places playing for Manchester United against PSV Eindhoven last month.
John Stones will also have the opportunity to add to his six caps. The Everton defender is joined in the party by Manchester United centre-back Phil Jones, who has recovered from a blood clot in his calf.
On Ings, England coach Roy Hodgson said: "Danny is someone we followed very closely at Burnley last year but didn't have a chance to bring him in because of the Under-21s - we never felt we could rob them to have him with us - but now is a good opportunity to bring him in.
"Dele is, I suppose, the more offbeat one in the sense he's so young and has only just broken into the Tottenham team, but we're very impressed with what we've seen. It's a good opportunity with so many midfielders away through injury. Who knows where he will end up? He's a very exciting talent."
