A left-arm spinner, Ferley found opportunities hard to come by at Nottinghamshire in 2008 due to the presence of Graeme Swann and Samit Patel.
Ferley went on the England Under 19 tour to India in 2000-01 and took 4-32, including three wickets in nine balls, to help England to victory over India U19 in the second one-day international at Vijayawada.
A product of Durham University, he was chosen for the British Universities tour of South Africa in 2002.
Made his debut for Kent in the County Championship against Surrey at The Oval in 2003 and claimed figures of 4-76.
Struggled to secure a regular first-team place though and failed to make a Championship run out in 2005 due to the fine form of Min Patel, although he featured more prominently in the one-day game.
He was given an extension to his contract with Kent at the end of the 2005 season but signed for Nottinghamshire at the end of 2006.
Ferley only featured in three county championship matches in 2007 but hit 43 not out and finished with a batting average of 83 but only one wicket.
His left-armers were an effective weapon in 2008 Twenty20, his nine scalps coming at an average of just 18.
But other opportunities were few and far between, and he declined a new two-year deal to move back to Kent for the 2009 and 2010 seasons.
