Due to delays on the installation of the floodlights at Bradford & Bingley's Wagon Lane ground the league and competition sponsors, Dyson Insulations, have agreed for the ties to be played on the grounds of the four group winners.
The ties have to be played before August 18 and the host clubs will be responsible for arranging when their game is played. If a date cannot be agreed, matches will revert to the original date set in the fixture list.
The semi-finals will still go ahead under lights at Bradford & Bingley on August 18 and 19 with the final on Thursday, August 20 with matches starting at 8pm.
Group Three winners Heaton will entertain Group One runners-up Pudsey St Lawrence and Cleckheaton travel to Farsley, while East Bierley entertain Yeadon after they overcame Saltaire by 20 runs in their final group game on Wednesday. Yeadon made 140 and restricted Saltaire to 120.
Quarter-final draw: East Bierley v Yeadon, Hanging Heaton v Pudsey SL, Farsley v Cleckheaton, Bradford & Bingley v Bankfoot.
