A final day shootout will determine who progresses from group A.
There was further shock results in the Laois senior hurling championship.
26 times winners and champions as recently as 2018, Camross are out.
They suffered defeat to intermediate winners from last year Rosenallis, 2-20 to 3-9.
Cillian Callaly says it was a big win for the club:
It means Borris/Kilcotton are the first team to seal progression from group B, with Ballinakill and Rosenallis bidding to join them on September 13th.
In group A, there was wins for Clough/Ballacolla against Abbeyleix and Rathdowney/Errill over Castletown.
That means Castletown are out and the remaining three teams will battle over the top two places in the final round of games.
