United failed to make this stage of any knockout competition during their inaugural season last term, so are determined to extend a cup run which has already included convincing away wins at Nantwich and Colne.
Silsden currently lie 11 places and 31 points behind United in North West Counties League Division One, but put up a good display when losing 4-2 at Gigg Lane earlier this season, having had to play the last hour with 10 men. With a bumper home crowd expected in West Yorkshire, United do not expect an easy passage to the semi-finals.
Atherton LR are hosts to Abbey Hey, who are a place and four points above them in Division One, but the Crilly Park outfit have four games in hand on their rivals.
They will be aiming to avenge the 3-1 defeat when they visited Abbey Hey earlier in the season. Extra spice is added by the return of Hey boss Mike Lester, who walked out on Atherton LR this time last year, taking most of the players with him.
Rovers will be counting on veteran striker and new arrival Chris Bermingham to continue his fine form after scoring on his debut in their 2-1 win at home to Colne.
Division Two side Daisy Hill have not played since January 27. They take on Holker Old Boys who are a place above them.
Atherton Collieries must overcome the disappointment of their semi final exit in the Goldline Trophy when they take on Bacup Borough at home on Monday night.
