The Division 2 final pairing will also be decided this afternoon.
League leaders Monaghan know a win over Down will send them into the decider but the Mourne Men need a victory to avoid the drop.
Elsewhere Roscommon take on Westmeath with a chance to make the final while their opponents have nothing to play for
Meath and Cavan could still make the final if they win their matches against Louth and Cork and hope other results go their way.
All four matches will get underway at 1:30pm.
