Depending on how other results go in Division 1, a home win for Cork following their Round 5 win over Monaghan could even move them into the top four ahead of their final-round derby date with Kerry.
Down, in turn, could be relegated tomorrow if things go against them at Páirc Uí Rinn following a terrible campaign that has yielded five defeats from five outings.
Cork’s substitutes will be confirmed today and will include experienced duo Michael Shields and Daniel Goulding as well as talented attacker Brian Hurley, despite all coming on in the win over Monaghan.
Mayo are currently in the bottom two alongside Down and have drafted in defender Chris Barrett and attackers Conor Loftus and Evan Regan for their trip to Roscommon.
The five-in-a-row Connacht champions badly need a win at Dr Hyde Park and boss Stephen Rochford has dropped the axe on Donal Vaughan, Kevin McLoughlin, and Cathal Carolan.
Cavan, lying joint second in Division 2, are unchanged for the visit of Laois to Kingspan Breffni Park.
Fellow Ulster outfit Derry have similarly resisted the temptation for change as they seek a win over visitors Meath to keep their own promotion hopes alive.
Meanwhile, three-in-a-row league winners Dublin will confirm their lineup for this evening’s Croke Park tie against Donegal at midday.
