The 18-year-old is one of a number of young players included in the group by Pep Guardiola.
Manchester City's World Cup representatives could miss the Community Shield tie against Chelsea and Premier League opener against Arsenal as they recover from a sustained period of club and worldwide action, manager Pep Guardiola has said.
First team stars such as Kevin De Bruyne, Sergio Aguero, Vincent Kompany, Ederson, David Silva, Gabriel Jesus, Raheem Sterling, Kyle Walker and John Stones have not made the journey to compete in the annual International Champions Cup pre-season tournament with most not expected back until a week before the start of the domestic season in England.
Despite being told again he is surplus to requirements at City, Hart is away on their pre-season tour of the USA and played in last night's 1-0 defeat to Borussia Dortmund. I know it is not easy for him, what happened in the last period.
"But he is with us". We tried, but players have to go where they go.
Also in the squad is City's summer signing Riyad Mahrez, the winger recruited for a club-record fee of £60million from Leicester.

The Citizens are still reeling after losing out on Jorginho to Chelsea, having long thought that the Italy global wanted to move to the Etihad Stadium.
Regarding Jorginho, Guardiola said: "I'm not disappointed".
"English football receives an exceptional player. All the best for him".
"Leroy has to accept that this decision may make him stronger".
