Glenavon's Mark Sykes delivered a 1-0 win for Northern Ireland U21s in their final UEFA U21 Championship qualifying game against Slovakia at Windsor Park, although they narrowly missed out on a play-off place.
Northern Ireland still had a chance of making the play-offs at kick-off and their hopes were only ended with 30 minutes to play in Belfast, as Portugal snatched the final play-off place with a 4-2 win over Bosnia and Herzegovinia.
The Windsor win was not fruitless as it was enough for NI to leapfrog their opponents into second spot in Group 2 - a fitting end to a thrilling campaign.

NI had been denied a first half penalty when Paul Smyth looked to be brought down as he cut in from the left wing.

Soon after, Sykes went one better and NI were able to see out their sixth victory from their 10 qualifying matches.
Here's all the action on a day of permutations as it happened:
