Dundalk have dismissed head coach Vinny Perth.
The clubs owners, American based investment group Peak 6, decided on Thursday evening to part company with the Dubliner.
The decision comes on the back of the Lilywhites' disappointing Champions League qualifier defeat to Slovenian side Celje.
The League of Ireland champions were beaten 3-0 in the one-off game in Hungary on Wednesday evening, a result which could have major implications for their financial planning.
No announcement has been made about a successor, with 10 league games still left to play. The Irish champions remain in the Europa League, where they will play in a qualifier next month.
In a statement, the Dundalk board thanked Perth for his seven-and-a-half years service with the club and wished him well for the future.
Assistants John Gill and Alan Reynolds will take charge of first team affairs until further notice.
Under Perth, Dundalk struggled for form after coming back from lockdown. They are yet to win in the SSE Airtricity Premier Division since the resumption and remain eight points adrift of Shamrock Rovers in third place as their title challenge fades.
Perth took charge of Dundalk at the start of 2019 after six years as Stephen Kenny's assistant and led his side to the Premier Division title in his first season in the hot-seat.
However, last night he accepted that results and performances hadn't been good enough since their return and admitted that his position could be under threat.
Asked about his future, the 44-year-old said: "It’s a fair question. I ultimately respect that I’m at a club that is trying to do things. We’ve rolled the dice.
"It’s not easy, but if we just wanted to be like most teams and dominate domestically, and do OK in Europe by winning a round and losing a round, then I think that could have been done, but we rolled the dice and we built a European squad or the beginnings of a European squad.
"That has caused us problems with Covid-19, but there’s no doubt that that falls at my door and, ultimately, I’m big and ugly enough to accept it, but what will be, will be."
