Harrison to leave New Road
Nick Harrison will be released by Worcestershire at the end of the season.
The 22-year-old seamer made his debut for the Pears in 2011 but has since made just three first-class and seven List A appearances for the New Road club.
Worcestershire's chief executive David Leatherdale said: "It is always hard when players' contracts are not renewed.
\"But it is hoped by informing Nick early he will have the best opportunity to find another county as he will be available to play during the remainder of this season if an opportunity arises."
