The game ended in a scoreless draw when failing light prevented its continuation long enough to reach a decision.
Draws for the first county championships were made at the meeting in the G.A.A. Rooms, Collooney, on February 12th 1888. Eighteen clubs affiliated, including newly founded units.Collooney affiliated on November 11th 1888 and D.P Bree and John Philips of Collooney were elected among other.
