Europa League play-offs to take place on 8 May and 12 May
The Irish Premiership's Europa League play-offs will take place on Monday 8 May and Friday 12 May.
The play-offs semi-finals on 8 May will see the fourth and seventh-placed clubs in opposition with the fifth and sixth-placed also meeting.
The higher ranked team in the regular season will have home advantage for the 12 May final.
Cliftonville, Ballymena United, Glenavon and Dungannon Swifts are certain to be the play-off teams.
However, the semi-final pairings have still to be decided going into this weekend's final round of fixtures.
The Premiership promotion/relegation play-off, over two legs, will take place on Tuesday 9 May and Friday 12 May.
Carrick Rangers are certain to be involved in that fixture when they will face the winner of the Championship play-off which will involve Institute and either Ballyclare Comrades or PSNI.
Meanwhile, the Irish FA has announced club licensing for the Irish League 2017/18 season.
As was the case this year, Uefa Cup licences have been awarded to nine of this season's Premiership teams with Ards, Carrick Rangers and Portadown merely having the requirements for Premiership licences.
Ballymena United and Dungannon Swifts will play Europa League games at Seaview if they win the upcoming European play-offs.
Dundela, Bangor, Newington YC and Tobermore United have been refused Championship licences but none of those clubs are in contention for promotion from the Premier Intermediate table.
