Derbyshire have re-arranged their abandoned Chesterfield Festival matches against Durham and Nottinghamshire for September following bad weather. The festival will begin with a Pro40 game against the Dynamos on 4 September and will continue with a Championship fixture against Notts from 6 September.
Chief Executive Tom Sears said: "We are delighted that we have been able to reschedule the Chesterfield Festival.
"We look forward to a very successful week, albeit later than planned."
