Killeen holds the Friends Provident Trophy aloft at Lord's in 2007
Durham seamer Neil Killeen has ended his 16-year playing career with the county to concentrate on coaching.
Killeen, 34, made his debut for Durham in 1995 and turned out for his final appearance in Saturday's CB 40 defeat by Kent.
"It was a tough decision to call time on my career," said Killeen.
"I'm excited about the opportunities ahead especially those that will see me continue to work alongside some of the quality talent we have here at Durham."
Killeen added: "I've had a wonderful career at Durham and enjoyed every minute of it.
"I'd like to say a huge thank you to all the players, staff and members for their support over the years."
Killeen was part of the side that lifted the Friends Provident Trophy at Lord's in 2007, beating Hampshire to become the first side in the county's history to win major silverware.
For him to retire as the leading wicket taker for Durham in one-day cricket is certainly an accolade that is much deserved
"My absolute highlight has to be winning the Friends Provident Trophy at Lord's," Killeen continued.
"It was great seeing the hard work of so many people coming into fruition; it was a massive achievement for the team and that weekend is something I will always remember."
Head coach Geoff Cook said: "I've enjoyed watching Neil play cricket throughout his career and for him to retire as the leading wicket taker for Durham in one-day cricket is certainly an accolade that is much deserved.
"He has worked extremely hard to give his best to the team and the club over the last 16 years and I'd like to wish him all the best with his future projects."
Killeen ends his playing career having made 226 one-day, 102 first-class and 45 Twenty20 appearances for the county as a one-club man.
