Wibsey were condemned to relegation from the West Riding County Amateur League Premier Division in midweek as leaders Ovenden West Riding marched towards the title with an 8-1 victory.
Who joins the Bradford in dropping down a level is between Brighouse Town, Littletown and Mirfield-based Lower Hopton.
The latter side look the most likely as they have only one game left to play.
Brighouse host Steeton – who enjoyed an impressive 6-2 win at home to Campion on Wednesday, with Lee Reilly (pictured) bagging a hat-trick – on Saturday, while Littletown visit Storthes Hall.
Salts could clinch second place in Division One with a victory over visitors Tingley Athletic if Overthorpe fail to beat Wakefield City.
With a 6-5 midweek home win over Bay Athletic reserves, Dudley Hill Rangers need only one point from their home game with Storthes Hall Reserves to secure their place in Division One next season. That would relegate their visitors, who only won promotion last season back into Division Two.
Hunsworth won 3-2 at Bronte in Wednesday’s other match.
Campion reserves, who occupy second place in Division Two and are six points behind Albion Sports, could draw level at the summit with wins at Golcar United reserves and at home to West Horton next Wednesday. That would set up a title decider in the last game of the season at Sports.
On Monday, Campion and Bay Athletic meet at Manningham Mills in the quarter-final of the Premier Division Cup.
