NIFL Premiership play-offs
The runners-up and third-placed teams from the Championship were set to take part (over two legs) in the Championship promotion pre-play-off. However, the third-placed team, Harland and Wolff Welders, did not apply for a Premiership licence, so the second-placed team Newry City moved directly into the play-off final.
Dergiew won 4–1 on aggregate and retained their position in the NIFL Championship with Queen's University remaining in the NIFL Premier Intermediate League.
