Shane Ferguson and Jimmy Abdou have both answered their country's call ahead of the next round of international fixtures.
Ferguson, who has been used as a left-back and winger in Michael O'Neill's Northern Ireland squad, will be available for selection when the Green and White Army host New Zealand in a friendly next week before travelling to Azerbaijan for a crucial World Cup Qualifier on June 10.
Northern Ireland are sitting second in WCQ's Group C, four points ahead of Czech Republic with five matches still to be played.
Meanwhile, Lions and Comoros midfielder Jimmy Abdou will travel to Togo on June 4, playing a friendly in preparation for their Continental Qualifier in Malawi a week later.
