A Loss would condem the Lake County to relegation.
Westmeath will hope to keep their faint survival hopes alive in the National Hurling League Division 1B this weekend as they host Waterford in Cusack Park.
The Lake County have endured a difficult season so far having lost all four league matches.
Waterford meanwhile have recovered well from their shook opening day loss to Carlow, The Deise will be targeting promotion after picking up three sucessive wins.
However Westmeath boss Seoirse Bulfin says his side can take positives from their performance over Offaly heading into Sunday's clash.
The match throws in at two o'clock at Cusack Park on Sunday.
