Donegal's first Ulster championship match will be on the weekend of June 26/27

Donegal's first game in this 2021 Ulster GAA Football Senior Championship will be played Páirc Esler, Newry on the  

weekend of Saturday 26/Sunday 27 June 2021.

If Donegal defeat Down in the preliminary round, it would set up a tasty quarter final game in MacCumhaill Park against Derry on the weekend of July 10-11, but that is not something that the Donegal management or team would contenance at this stage, as it has been the failure of many a good team in the past.

Quarter Final 1 (Saturday 03 July / Sunday 04 July)
