The eighth team in next year's Robinson Services Premier League will be decided, a straight fight between Lisburn and Holywood to replace relegated Armagh.
Both the top two in Section One are at home, with Lisburn four points ahead of their rivals, although Holywood have a better run rate, so if they beat Cregagh and Adam Berry's side lose to Donaghcloney Mill then it will be the Seapark men who will claim the title and promotion.
Interestingly, Holywood have opted for an 11am start, 30 minutes before the game at Wallace Park gets under way.
The momentum is certainly with Holywood, who have won their last six matches including last week against third-place Bangor, which ended the Seasiders' hopes of promotion.
Even a huge Lisburn win is unlikely to save Laurelvale from relegation to Section Two. They are currently four points adrift at the bottom with a substantially inferior run rate and two teams go down.
Lurgan must beat Bangor and hope Lisburn win to give the Pollock Park club a last-day reprieve. In that scenario, Donaghcloney Mill would be relegated.
There are also two Premier League fixtures tomorrow, remarkably between the same two teams.
Muckamore and Waringstown have yet to meet this season and have agreed to play the two games as 20-over matches at Moylena, the first at noon.
The remaining two Premier League games will be played on Sunday, with Waringstown again in action, at home to Civil Service North. The Irish Cup holders need to win only one of their three games to seal runners-up spot behind CIYMS, while Armagh play their last top-flight match for at least two years at home to North Down.
