The Extra.ie FAI Cup quarter-final schedule has been altered due to Irish involvement in the Tunnock's Caramel Wafers Challenge Cup and international call-ups.
Two games will proceed as normal. First Division side Galway United will face Shamrock Rovers on Friday 6 September with kick-off at 7.45pm at Eamonn Deacy Park.
Sligo Rovers will host UCD in the Showgrounds on Saturday 7 September with kick-off at 7.45pm.
However, Waterford v Dundalk will take place on Monday 9 September with kick-off at 7.45pm.
That date is due to the Blues playing Hearts Under-21s in the Challenge Cup at the RSC on the previous Friday.
Manager Alan Reynolds has voiced his displeasure at the decision to move an FAI Cup game because of the Scottish tournament.
He told the Irish Mirror: "The FAI Cup is a massive competition and if we play on a Monday night with the kids back to school, the crowd will be down.
"Playing a Cup quarter-final on a Monday night is poor.
"If the game against Dundalk is on Monday it will possibly be the Under-19s (against Hearts)."
Crumlin United v Bohemians will take place on Monday 16 September with both the venue and kick-off time yet to be confirmed.
The match would have taken place on the weekend beginning 7 September, but Bohs are away to Airdrie in the Scottish competition.
However, the north Dublin side have two players in the Republic of Ireland Under-21 squad, meaning they could have requested a postponement of their FAI Cup fixture.
Instead they will play the game with Airdrie and just do without their international stars, Darragh Leahy and Danny Mandroiu.
That encounter is set to take place on Saturday 7 September, just outside Glasgow.
Meanwhile in the Premier Division, Dundalk v Cork City, postponed earlier in the season because of European matches, has been rescheduled for Friday 6 September as well.
That means Dundalk are now in the midst of a run of 12 games in 38 days, which started with their first game in August against Slovan Bratislava and will end on 14 September in the EA SPORTS Cup final with Derry City in The Brandywell.
It will be extended to 13 games in 41 days if a replay is required in the FAI Cup tie.
Potential replay dates if required:
- Shamrock Rovers v Galway United – Monday 9 September, Tallaght Stadium, 7:45pm
- UCD v Sligo Rovers – Tuesday 17 September, UCD Bowl, 7:45pm
- Dundalk v Waterford – Tuesday 17 September, Oriel Park, 7:45pm
- Bohemians v Crumlin United – Monday 23 September, Dalymount Park, 7:45pm
