Donegal have been all but relegated from Division One after suffering a heavy home defeat to Mayo.
And Monaghan look most likely to join them in Division Two next year after losing to Tyrone in Clones having suffered two red cards.
To stay up, Donegal would have to score a big victory over Roscommon next Sunday while hoping that Monaghan draw with Mayo, who are now assured of a spot in the Division One final, and Armagh lose to Tyrone.
