Waterford United are to appeal the result of the Airtricity League play-off against Dundalk.
The Blues claim Dundalk's Michael Rafter was inaccurately registered by the Lillywites when they signed him this season.
Waterford will be hoping to see the result overturned, possibly securing Premier Division status for Waterford.
Dundalk defeated Waterford 4-2 on aggregate following their 2-0 away win on Friday night.
