England boss Gareth Southgate has called up Ben Chilwell and Demarai Gray for Tuesday evening's friendly against Switzerland at the King Power Stadium.
The Leicester City pair are in line to make their senior international bows at the home of their club side, having been promoted from the Under-21s setup.
Southgate suggested after Saturday's 2-1 UEFA Nations League loss to Spain that he would consider adding to his squad, with Luke Shaw returning to Manchester United due to concussion, adding to the losses of Adam Lallana and Raheem Sterling.
Chilwell and Gray were part of Leicester's title-winning side in 2016 and are included in the senior England fold for the first time.
Uncapped Fulham goalkeeper Marcus Bettinelli was also called up for the first time earlier this week, but was unused in the narrow defeat to Spain.
