The GAA's commercial director Dermot Power is to leave his position in September, the Irish Independent understands.
Power is retiring and his role will now come under the brief of Croke Park stadium director Peter McKenna. The move is expected to be confirmed at Congress over the weekend.
Power has been head of the commercial department in Croke Park for the best part of 20 years and has overseen huge change in the GAA's sponsorship and media rights, as well as the initial sale of corporate boxes and premium seats in Croke Park.
Last year commercial revenues were worth €19.75m, with media rights worth €10.8m and sponsorships generating nearly €8.2m.
The addition of the commercial brief for McKenna and his stadium team follows on from their takeover of seat and box sales at Croke Park.
Earlier this week, Power and his team finalised the addition of eircom as one of the three football championship sponsors.
