Former West Indies seamer Corey Collymore is to leave Middlesex.
Collymore, 35, who has taken 86 first-class wickets in his three years at Lord's, will not be offered a new contract for next season.
Middlesex's managing director of cricket Angus Fraser said: "He is a wonderful pro and an exceptional man...proud, honest, hard-working and has set a wonderful example to our young and seasoned cricketers.
"At Middlesex, we are fortunate enough to have a number of talented young fast bowlers who need to be pushing for first-class cricket.
"The challenge for them is to seamlessly fill the hole created by Corey's departure."
