The Unite the Union Champions Cup has been cancelled due to "scheduling issues".
Unite the Union, the Irish Football Association and Football Association of Ireland had planned to run an expanded four-team tournament in 2021.
But the impact of the Covid pandemic saw the semi-finals of the competition put back until this year, and now a decision has been made to scrap it altogether.

Talks will now begin on the future of the competition itself and other initiatives.
Irish FA President Conrad Kirkwood said: “We will continue to work with our partners on this and other ventures that place an important value on community as central to our game.”
Unite the Union Deputy Regional Secretary Davy Thompson said: “Whilst we are disappointed that the tournament couldn’t be concluded, we do acknowledge the pressures on clubs, players and staff coupled with the split seasons and the difficulties this brings when trying to organise a competition of this nature.
“Covid is something that no-one could have envisaged as we entered into this project and has played a significant part in this outcome. We will continue to work closely with both associations and the clubs to advance our community activities which were at the core of this competition.”
League of Ireland Director Mark Scanlon said that following on from the Covid-19 enforced postponement of the semi-finals late last year it had proven difficult to find alternative dates for the semi-finals and final of the Unite the union Champions Cup 2021.
He said: “Together with Unite the Union and the Irish FA we have had to make the difficult decision to phase out the tournament.
"On behalf of the FAI and our League of Ireland clubs, I want to thank Unite the union and the Irish FA for their ongoing support and consideration in reaching this decision.
“The commitment of Unite the union to football and their incredible work in the community with our clubs has been inspirational and we thank them for that. We will now work with all stakeholders on the off-the-field initiatives that have already proven so popular.”
Linfield, Coleraine, Shamrock Rovers and St Patrick's Athletic were due to play in the 2021 tournament, with two regional semi-finals and a final at the Aviva Stadium.
The cross-border competition was thrown into turmoil last November as Shamrock Rovers and St Pat’s were in the dark as to when the matches would be played.
As it was the end of the domestic League of Ireland season - and St Pat’s had the FAI Cup final to consider - it was a struggle for all sides to settle on dates.
In the end, organisers postponed the matches citing Covid concerns on both sides of the border.
The Champions Cup was first run in 2019 with Dundalk beating Linfield in a two-legged final.
The competition wasn't held in 2020 due to the Covid-19 pandemic.
