Former England bowler Boyd Rankin has left Warwickshire after more than a decade with the club, having signed a central contract with Ireland.
Rankin joined the Bears from Derbyshire in 2008, winning promotion from Division Two in his first season, and went onto win the County Championship in 2012.
He made his Test debut for England in 2014, during the ill-fated 2013-14 Ashes tour, but made no more appearances after that.
Having played for Ireland between 2007 and 2012, he returned to the Irish fold in 2015 and took their first ever Test wicket when they played Pakistan in 2018.

"I have absolutely loved it," he said. "I have been really lucky to spend 15 years in county cricket and 11 at Warwickshire.
"It was with the Bears that my career really took off. When I came to England I was all over the place.
"I was unfit and didn't really understand what was needed to be a professional cricketer.
"Mike Hendrick, at Derbyshire, got me moving in the right direction and then I joined the Bears and I owe the bowling coaches I worked with there so much.
"It has been brilliant to play on the world stage for 10 years and they take a lot of credit for that."
