Armagh, Fermanagh and Cavan have been penalised for fielding ineligible players in the Dr McKenna Cup.
Armagh and Fermanagh have had their Round 2 victories overturned after being found to have breached the pre-season third level policy by the Ulster CCCC.
Fermanagh had edged out Cavan in their 1-12 to 1-10 victory on Wednesday evening, while Armagh claimed a 3-10 to 0-10 victory over Down.
However Ulster GAA have announced that due to the "fielding of ineligible players", both of those results have now been scrapped.
While the outcome of the Down-Armagh game is reversed, with the Mourne County awarded the points, the Fermanagh-Cavan tie has been ruled null and void, so no points awarded to either team.
Ulster GAA did not reveal which players were found to have been ineligible for the round of fixtures, with restrictions placed on players lining out for county and third-level teams in a short period of time.
