The first leg of Shelbourne's Champions League qualifying round tie against Linfield will be broadcast live on RTÉ on Wednesday, 9 July.
The reigning SSE Airtricity Men's Premier Division side will kick off their European campaign in the first qualifying round of UEFA's elite club competition and are unseeded against the NIFL Premiership champions.
The first leg will be shown on RTÉ2 and RTÉ Player with a 7.45pm kick-off.
Shelbourne's return to the Champions League qualifiers after a two-decade absence comes after the shock resignation of manager Damien Duff on Sunday.
The Republic of Ireland great, who had led the Dublin club to a first League of Ireland title in 18 years last season, left Tolka Park amid an indifferent title defence that has left them in midtable.
Duff's assistant and fellow former Boys in Green international Joey O'Brien took interim charge of Shels on Monday night for their 2-2 draw at Waterford.
Asked afterwards if he would like to be the long-term successor as manager, O'Brien was non-committal, saying that Duff's departure had come as a shock to the system for all at the club.
"It was a shock for everyone at the football club, myself included," he said.
"Listen, from a personal point of view I absolutely loved the manager and he'll always be my manager. We had some great times and he built this really and the success we've had over the last few years, I don’t think it would have been possible without him."
RTÉ will not broadcast the second leg from Windsor Park on 16 July, with the winner of the tie advancing to a second round tie against Qarabag of Azerbaijan.
Meanwhile, Linfield have confirmed that their away allocation for the first leg will be just 280 tickets, due to the UEFA limits on Tolka Park's capacity.
"The club is extremely disappointed at receiving such a limited allocation for such an important and eagerly anticipated game, however this is completely out of our control," said the Belfast club in a statement.
It is not yet known what Shelbourne's away allocation will be for the second leg.
