Northamptonshire have confirmed the release of Blessing Muzabarani, Tom Sole and Brett Hutton.
Zimbabwean Muzabarani, 24, originally joined the county on a three-year Kolpak registration but leaves with a year remaining on his contract.
Scotland international all-rounder Sole, 24, featured in just three T20 Blast matches last season.
Former Nottinghamshire right-arm seamer Hutton, 27, leaves after turning down a contract extension earlier in the year.
Changes from next season following Brexit mean Northants would only have been able to retain Muzabarani’s registration if he became an overseas player.
