A solitary point separates the top four teams in Group 1, with Crawford’s side currently sitting in second place, behind Italy only on goal difference.
Ireland Under-19 international Mark McGuinness is called up for the first time, and joins the uncapped group of Ed McGinty, Luca Connell, Anthony Scully and Joshua Kayode.
Senior internationals Lee O’Connor, Jason Knight, Michael Obafemi and Troy Parrott are also included in Crawford’s squad for the two matches.
Despite making his debut last month, Southampton midfielder Will Smallbone misses out on the upcoming two games with injury.
“It’s a massive two games”, Jim Crawford told FAI.ie. “A top two finish is still within our hands in this group, and that’s a brilliant position to be in, going into these matches.”
“We’ll miss the lack of fans in Tallaght Stadium for the Iceland game, but we hope to put on a show for the fans in both games, and qualify for the European Championships.”
