Glamorgan batsman Mike Powell has been released by the county after 15 years of first-team service.
The 34-year-old, currently in his benefit year, promised to "prove the doubters wrong" this season by scoring enough runs to warrant a new contract.
He scored 675 runs in 23 Championship innings at an average of 32.14, making him Glamorgan's fifth-highest scorer.
But Glamorgan have decided to pursue other options and Powell said: "It's a shame it's come to an end."
Powell helped Glamorgan to the 1997 County Championship in his first season before winning two one-day titles in 2002 and 2004.
He feels he still has plenty to offer in the County game, saying: "I certainly feel I'm fit and fresh enough to play for at least another two years."
Powell's Glamorgan career began with an unbeaten double hundred against Oxford University as a teenager.
He came within 11 runs of breaking Steve James' record for Glamorgan's highest innings by scoring 299 against Gloucestershire in 2006, but a year later he became critically ill.
A blood clot in his shoulder forced Powell to have a rib removed, but complications following the surgery left him fighting for his life. He made a full recovery and buried the rib in the outfield at the Swalec Stadium.
The heath scare, he says, allows him to take a more philosophical look at the disappointment of failing to secure a new contract.
"Once you've been on life-support for three or four days, losing your job pales into insignificance really," Powell told BBC Sport Wales.
"Coming back and playing after that injury, it's very close to me and I'm very thankful I came out the other side."
Overall Powell, from Abergavenny, hit 25 centuries in a first-class total of 11,427 runs at an average of nearly 40, as well as scoring 5,425 runs in the various limited-overs competitions - sharing many hard-hitting partnerships with Matthew Maynard in particular.
"It was a successful time and a good time to be involved at the club, the boys that played then were tough, hard cricketers," he said.
"I was very proud to be part of that Glamorgan side from '97 on led by Maynard, with the likes of Steve James, Steve Watkin and Robert Croft to name but a few."
