Ramiro Funes Mori has missed the cut for Argentina's 23-man squad for the World Cup
Sigurdsson makes the cut for his country's first ever trip to the Finals despite missing the last few weeks of the Premier League season with a knee injury.
The 28-year-old suffered damage to his right knee during an innocuous passage of play in the home win over Brighton & Hove Albion in March but has been making good progress and is confident of being fit for the World Cup.
He joins Jordan Pickford and Idrissa Gueye in being called up for Russia by his country but there is no place in Argentina's final 23-man squad for Funes Mori.
The defender was a regular first-choice starter for the Albiceleste prior to his own knee injury that sidelined him for almost a year.
He recently returned to Everton's team and was agitating for more game time with the Blues from Sam Allardyce in the final weeks of the campaign because he feared missing out on the World Cup.
He started his first game of the season in the final-day defeat at West Ham having made a couple of substitute appearances prior to that but it was not enough to earn a place in Argentina's squad.
Nikola Vlasic and Oumar Niasse are two more Blues players who didn't make their country's squads for Russia.
