Roscommon find themselves in a relegation battle having been semi-finalist for each of the previous three seasons.
The Connacht outfit were pitted with Laois and Kildare in the group stages, losing out to both Leinster sides.
Longford meanwhile, began their Championship campaign in sensational fashion with victory over 2020 finalists Westmeath but suffered defeats to Wexford and Sligo.
Sunday isn’t necessarily the end of the road for either side, however. The winners will stay up, while the losers will have a second chance to preserve Intermediate status against Offaly or Fermanagh.
Roscommon have struggled in attack, with their leading scorer, Rebecca Finan, on 0-5. Longford skipper Michelle Farrell is leading the way in the scoring stakes with 1-6 to date in the Championship.
Roscommon: H Cummins, R Brady, S Kenny (c), M Kelly, E Irwin, R Wynne, S McVeigh, J Higgins, C Conway, L Fleming, A MacAuliffe, J Cregg, R Finan, N McHugh, R Fitzmaurice
Longford: R McGrath, K Crawford, L Keegan, A Cosgrove, O Nevin, E O’Brien, C Farrell, N Darcy, K Shannon, L Monaghan, S Shannon, M Farrell (c), A Darcy, E Heaney, C Healy.
