King has been named in the Norwegian Under-21 squad for their UEFA Under-21 qualifying match against Azerbaijan on June 1st.
The Norwegians still have an outside chance of reaching the finals in the Czech Republic in June 2015, but they need maximum points in Baku to close the gap on the teams above them and finish one of the best placed runners-up.
However, when the two sides met in Dramman last September, Azerbaijan ran out 3-1 winners.
Receiving an international call-up for the first time at Under-21 level is Darragh Lenihan.
The midfielder turned defender has been selected to represent the Republic of Ireland in a friendly match against the Qatar olympic squad in Aachen, Germany on May 24th.
Lenihan, who has been on the fringes of the first team with Rovers this season, has previously represented Ireland at all levels up to Under-19.
