Josh Davey and Adam London are free to seek new counties after being released by Middlesex.
All-rounder Davey has made 23 first-team appearances in four seasons at Lord’s, featuring predominantly in white-ball cricket but contributing three half-centuries in four LV= County Championship outings.
The 23-year-old has also gained 12 caps for Scotland and returned outstanding figures of 5-9 against Afghanistan at Ayr in 2010.
London, 24, joined Middlesex’s professional staff from the club’s academy in 2008 and went on to average 28 in 12 first-class games.
Angus Fraser, Middlesex’s managing director of cricket, said: “Releasing Adam and Josh was a tough decision. They are both good cricketers who have come through our youth system and are fine young men.
“However, young cricketers do get to an age when they need to be playing regular 1st XI cricket. Adam and Josh are at this stage of their careers and are yet to claim regular first-team places.
“At Middlesex CCC we have several talented younger cricketers coming through and they now deserve the chance to push their credentials forward.
“Middlesex CCC thanks Adam and Josh for all their effort and time and wishes them well in the future. They will always be welcome at Lord's.”
