If the Portuguese are reluctant to risk Quaresma then Nani will support Cristiano Ronaldo up front.
Gylfi Sigurdsson, Aron Gunnarsson and Kolbeinn Sigthorsson were carrying injuries when named in Iceland's squad but have since proven their fitness.
Sigthorsson will be partnered by either Alfred Finnbogason or Jon Dadi Bodvarsson in attack.
Portugal and Iceland are the final two sides to get their Euro 2016 campaigns under way, while Saint-Etienne's Stade Geoffroy Guichard will be the last of the 10 venues to host its first game. It should be worth waiting for - Portugal's encouraging form under coach Fernando Santos means they begin as Group F favourites, but tournament debutants Iceland proved they are no respecters of reputation by beating the Netherlands twice in qualifying.
All seven of Portugal's qualifying wins came via single-goal margins and they struggled to find fluency in attack. But they arrive in France buoyed by a 7-0 win against Estonia last week in which key man Cristiano Ronaldo netted twice before being substituted at half-time. Ronaldo will win his 127th cap on Tuesday - equalling the Portuguese record set by Luis Figo.
Iceland's preparations also ended with a morale-boosting win against minnows - they beat Liechtenstein 4-0 - but there are question marks over their defensive strength. They have conceded 17 times in their last eight matches, losing 4-2 to Poland, 3-1 to Slovakia and 3-2 to Norway.
