Derbyshire's opening match of the County Championship against Surrey has had to be moved to The Oval because their ground is under water.
As a result of the change of the 19 April match, the return leg between the two sides will take place at the County Ground on 20 September.
Derbyshire chief executive Tom Sears said: "We've had exceptionally wet weather in Derby for six weeks.
"We looked elsewhere but all the county is in the same boat."
