Shamrock Rovers return to action following the sacking of Stephen Kenny when they meet Shelbourne in the FAI Ford Cup quarter-final in Tolka Park.
Defeat to Bohemians last Monday night in Tallaght Stadium proved the final game in charge for Kenny as the Hoops board brought an end to his tenure after just 10 wins in the league this year.
The Hoops are now 13 points behind leaders Sligo Rovers and are in dangerous of missing out on European qualification in the league, making cup competition success vital in the coming weeks.
Rovers are in next week’s EA Sports Cup final with Drogheda United and a place in the last four of the Blue Riband is at stake against Shels.
The sides met as recently as last Friday in the league with Paddy Kavanagh missing a glorious chance to claim a shock win for the Reds in the final seconds as the game finished 2-2.
Stephen Glass will take charge of the Hoops for the clash in Tolka Park and he will have to do it without Graham Gartland because of a back injury.
Glass said: "The players are all very much looking forward to the game. We know it will be a tough fixture, but we are all very keen to get to the semi-final of the FAI Cup.
"Training went well this week, but now the players just want to get on the pitch and focus on football and battling to get that semi-final place."
Shelbourne will have a full squad to select from for this game, reporting no injuries and both Glenn Cronin and Paddy Kavanagh return from suspension.
Alan Mathews is under pressure at Shels following a disappointing return to the top flight.
With just seven wins in the league and attendances plummeting, advancing in the cup is important to his chances of staying on next season.
He said: "It’s a huge opportunity for us to progress in the cup - another very big game for the club, Rovers coming here after being beaten by Bohemians.”
"We want to progress and want to make sure we pass this test. We’re going to have to step up to it, going to have to play better than we did tonight and last Friday to make sure we get the right result. They’re great games to be playing in, great games to be involved in – and we’re looking forward to it."
