Hanwell Town will travel to Ampthill Town in the fifth round of the FA Vase if they can overcome Ashford United in Saturday's re-arranged fourth round tie.
The fifth round ties are on February 15.
Hanwell have been locked in a struggle with Ampthill for supremacy in the Spartan South Midlands Premier League all season, with Town just behind in the table, but with games in hand. The sides drew 0-0 at Ampthill Park.
The Befordshire side won their fourth round tie on Saturday - beating Norwich United 3-1.
But Hanwell's bid to reach the last 16 was put on hold because of a waterlogged pitch at Reynolds Field.
If they overcome both Kent side Ashford and Ampthill, Hanwell will be in the quarter-finals and two games away from a Wembley final.
