Kurri Weston begin a must-win, three-game stretch to the finals by hosting the Tenambit Morpeth Bulls on Old Boys Day at Kurri Central.
Warriors captain Tyler Power said Old Boys Day was always a special day for the club and a successful one in terms of results in recent years.
"We really need to win our final three games to ensure we make the semi-finals again this year," Power said.
"We're hoping for plenty of support from our Old Boys on Saturday. We've got a barbie on for them and there's plenty of other food and refreshments on hand.
"We are equal on points with Northern Suburbs and Raymond Terrace and we all have games against each other over the next three weeks.
"We can't get ahead of ourselves as any stumble can end our chances."
Terrace hosts Norths in Saturday's one-day fixture.
Round 13's two-day fixtures sees Kurri Weston travel to Lorn Park to play Norths and the Lions host top side and reigning premiers City United.
In the final round Kurri Weston travel to Robins Oval to meet last year's grand final conquerors City United, Norths are on the road against Tenambit Morpeth and Terrace host Western Suburbs.
Other matches on Saturday include City United and Eastern Suburbs at Robins Oval and Western Suburbs and Thornton at Coronation Oval.
Easts need to win two matches to guarantee a spot in the finals for the first time since 2013/14.
