George Saville was named Northern Ireland's Man of the Match as the Green and White Army defeated South Korea 2-1 during March's international break.
On an afternoon that also saw Conor McLaughlin play 72 minutes, Saville was instrumental as Michael O'Neill's side won courtesy of a Kim own-goal and Paul Smyth's late effort.
Shane Ferguson was an unused substitute at Windsor Park.
Meanwhile, James Meredith was also unused as Australia lost 4-1 to Norway in Oslo and battled to a goalless draw with Colombia at Craven Cottage on Tuesday night - Tim Cahill was a 62nd minute substitute in The Socceroos' draw with Los Cafeteros.
Right-back Mahlon Romeo was in action as Antigua and Barbuda defeated Bermuda 3-2 and drew 1-1 with Jamaica, whilst Jordan Archer was an unused substitute for Scotland as they lost 1-0 at home to Costa Rica last Friday before winning 1-0 in Hungary on Tuesday night.
With the final international break of the season now complete, the septuplet will return to The Den for Friday's visit of Nottingham Forest in the Sky Bet Championship.
