Opening batsman Chris Taylor has left Yorkshire by mutual consent to focus on his business interests.
The club have released a statement which says the 28-year-old has departed to "pursue a personal ambition to be a successful entrepreneur".
Leeds-born Taylor runs a cricket coaching business alongside fellow Yorkshire player and newly-appointed captain Andrew Gale.
Taylor, who came through the Yorkshire youth set-up, confessed he had become frustrated at his lack of opportunities since rejoining the club from an impressive stint at Derbyshire in 2007.
"Following my successful stint with Derbyshire I genuinely thought I could make a real impact back at Yorkshire," said Taylor, who made his first-class debut for Yorkshire in 2001.
"However, I have been somewhat disappointed not to have played more first-team cricket.
"That said, I do realise there are some very exciting young cricketers emerging at the club and, as such, it is unlikely I will get any first XI opportunities in 2010.
"The last thing I want is to block the development of talented young cricketers making their way in the game."
Yorkshire chief executive Stewart Regan added: "Chris is a great guy and I am sorry that he has not had the breaks he needed to establish himself in our first team.
"I would like to thank him for his contribution over the last two years and wish him well in his new venture."
