Pontus Dahlberg (Sweden), Tiago Cukur (Turkey U21s) and Ethan Galbraith (Northern Ireland U21s) have received international call-ups.
Goalkeeper Dahlberg will be joining up with the 25-man Sweden squad for FIFA World Cup qualifiers against Spain (September 2) and Greece (September 8). The Swedish team will also play a friendly against Uzbekistan (September 5).
Galbraith and the young Northern Ireland team have a trip to face Malta on September 3 in the first of two UEFA European U21 Championship qualification matches. They will then host Slovakia U21 on September 7 in the same competition.
Cukur’s Turkey U21s also have two European U21 Championship qualifying matches hosting Belgium U21 and Scotland U21.
Due to the club receiving three international call-ups, Rovers' Sky Bet League One match against Cambridge United - which was due to be played at the Keepmoat Stadium on September 4 - has been postponed.
