Selston suffered a big blow to their title hopes as they fell to a surprise 4-0 defeat at home to mid-table Bilborough on Saturday.
The game was goalless at half-time but Bilborough took the lead early in the second period as Tariq Nadif fired home from 18 yards.
Nadif then added a second nine minutes later before Dean Bensley headed home from a corner on 72.
Jack Nicholson then rounded the win off a minute from time.
Selston remain top of the league but West Bridgford remain second, just a point behind and with two games in hand, Wollaton also ready to pounce being four points behind with four games in hand.
It was a bad day at the office for Awsworth Villa as they were crushed 11-1 at Burton Joyce.
