The big issue in J1A this weekend is the battle to avoid the relegation play-off while Sligo aim for the J1B title and the two J2 semi-finals also take place.
Galwegians currently occupy seventh place but a win over already relegated NUIG and a loss for Buccaneers at Connemara will see Buccs drop to second from bottom.
Ballina already have the title wrapped up and they travel to Ballinasloe ahead of the round-robin to qualify for a place in the All Ireland League next season.
There are only two games in J1B this weekend as leaders Sligo host Loughrea knowing a victory would secure them the title.
Third-placed Tuam host Creggs keen to earn the win that would move them closer to second spot and a promotion play-off.
The J2 League semi-finals take place this weekend as OLBC host Ballina with Corinthians travelling to Oughterard.
The two winners will go into the play-off final with the winners of that clash earning promotion and the losers going into a play-off against Claremorris, who finished bottom of J1C.
