Dundalk and Kildaren will meet for the second time this season on Sunday at the Kildares Sportsground.
It will be the first of two games in a row between the clubs.
A win would put the Drogheda side in contention for the League One title, while a draw would be their worst result in the competition.
It is also the first meeting between the two clubs since the Derry City v Derry Rovers fixture in October last year.

Conor O’Connor and Tommy Kelly went close for the Doolin side before Gannon fired over after a loose pass from Conor Houghton.

However, the Dairers were not deterred by a pair of Droglish crosses from the penalty spot, as McConahy headed the ball across goal.
It was a goal that they had to win for a point, but it was Dundalk who had the final say in the tie.
Paul Hartleys team came out on top again and got the better end of the ball in this one.
After the Dromans penalty in stoppage time, Kevin Doyle was on hand to head over from distance after Conor Kelly had fired past Sean Byrne.
Dundals defence held firm throughout and were able the penalty in order to secure the point.
Dundas goalkeeper Sean Maguire made a great save to deny Kevin Doyle from a shot after Conor O
