Both clubs have been involved in high scoring games in this year's championship.
Fireworks are expected when Portlaoise meet O'Dempsey's in the Laois Senior Football Championship semi-finals this weekend.
Portlaoise have been in excellent form through this year's campaign, dethroning defending champions St Joseph's with a 15 point win last time out.
O'Dempsey's have been more workmanlike in their progress through the championship.
After losing their opening game to Portarlington, the beaten finalists of 2022 have enjoyed wins over The Heath, Rosenallis, and Arles Killeen.
Former Laois footballer John O'Loughlin says he makes the 35 times champions the favourites, but he expects a competitive contest:
That game is the first of a double header in O'Moore Park on Sunday with the action set to start at 2.15pm, following that, Portarlington take on Graiguecullen at 4pm.
