Cork GAA has confirmed they reached a sponsorship agreement with British retail company Sports Direct in December.
Chairman Marc Sheehan said a deal had been concluded in early December 2020 with a formal launch set to take place at a later date.
It had been widely reported that Cork had agreed terms with the company to replace Chill Insurance as the inter-county teams' main sponsor in a partnership worth €400,000 a year up to 2025. There are also bonuses on offer if the Rebels enjoy All-Ireland success in hurling or football.
Sports Direct's CEO Mike Ashley is the owner of Premier League club Newcastle United.
Cork held their first county committee meeting of the year on Tuesday. In a meeting report published on Wednesday they said it was "a matter of regret to the Board that information had come into the public domain prior to the intended launch of this arrangement".
At the FAI's AGM just after Christmas, it was confirmed the soccer association will be repaying Sports Direct €100,000 a month until the autumn of 2025 after the company triggered a callback option on the €6.5m they gave to the FAI in 2016. Their sponsorship had not been due to begin until 2020.
