Durham must travel again in C&G quarter-finals
Durham's reward for ending Gloucestershire's remarkable run of one-day success is an away tie against Lancashire at Blackpool in the quarter-finals.
Somerset, after their stirring fourth-round victory over Glamorgan, must travel to Kent.
The other ties see Yorkshire entertain Warwickshire, and Worcestershire at home to Leicestershire.
One of the matches will be played on 24 July with the remainder on the following day.
