Wrenthorpe and Townville, last season's top two, are again are vying for the Premier Division crown.
Wrenthorpe, who visit relegation-threatened Batley, are one point ahead of defending champions Townville whose final game is at Wakefield City.
It is an intriguing finish because Batley will be desperate to avoid a return to Division One just 12 months after winning promotion.
They are one point ahead of second-bottom Wakefield St Michael's who have a difficult last match at Methley.
St Michael's need at least two points to have a chance of avoiding the drop. They have fewer six-point victories than Batley, a deciding factor if they finish level on points.
Promoted sides Liversedge and Carlton are battling it out for the Division One title.
Carlton, who lost top spot last weekend for the first time this season, visit Thornhill in their final fixture. They are one point behind Liversedge who host Moorlands.
One slight worry for Liversedge is that they have not collected maximum points since they beat relegated Wakefield Thornes on July 29. Despite skipper Simon Purdy's 87-wicket haul this season, they have only seven outright victories, compared to Carlton's 11.
Buttershaw St Paul's will hope for a double celebration on Saturday because both their sides are favourites to win championships.
Their first-team are involved in a thrilling finish to the Division Two title race where just two points divide Buttershaw, Mirfield Parish Cavaliers A and Hunslet Nelson.
Leaders Buttershaw host Woodkirk, while Hunslet Nelson visit Mirfield PC A in a last-day decider for promotion and possibly the title.
The only way Buttershaw could miss out on promotion is if they fail to collect a point and Mirfeld and Hunslet tie.
Buttershaw second-team travel to Hunslet Nelson A aiming to clinch the Division Four title. They are four points ahead of closest rivals Wakefield Thornes A who visit Hopton Mills A.
Third-placed Northowram Fields A visit fourth-placed Stanley A and they are both still in contention for promotion.
