Derbyshire have elected not to renew batsman Hassan Adnan's contract and the 33-year-old will seek a new challenge elsewhere for the 2008 season.
Adnan will be an honorary member after being capped by Derbyshire
Adnan made his debut in 2003 and the following season he scored 1,380 first-class runs at an average of 51.
In 2007, however, he averaged only 21 in his 11 first-class appearances.
"It's never nice informing players they have to go, especially when it is such a loyal servant and great team man," Derbyshire chief John Morris said.
