Uncapped winger Callum McManaman was the stand-out inclusion in Stuart Pearceâ€™s squad for Israel when it was announced on Tuesday.
But the 22-year-old damaged ankle ligaments that evening in Wiganâ€™s 4-1 defeat at Arsenal and faces three months on the sidelines.
Pearce has turned to Aston Villa forward Delfouneso, who was part of the Euro 2011 Under-21 squad in Denmark.
â€śNathan was very unfortunate not to make the squad in the first place,â€ť said Pearce.
â€śHe has contributed a great deal to the Under-21s in qualification and was unlucky that Callum McManamanâ€™s form was such that he had forced his way into the reckoning late on.â€ť
