Sussex batsman Rory Hamilton-Brown has announced his retirement at 27 after failing to recover from a wrist injury.
The former Surrey captain picked up the injury at the beginning of last season and his last appearance was a Twenty20 match against Middlesex on 27 June.
Despite surgery and rehabilitation he has been forced to call time on his 10-year professional career.
"I will leave the game with a heavy heart but many amazing memories and friends for life," he said.
"I would like to thank my family for their care and support over the course of my career."
The former England Under-19 player added: "I would also like to thank both Sussex and Surrey for giving me the chance to have the best job in the world for 10 years and all the coaches and staff that I have worked with along the way."
Hamilton-Brown made his first-class debut with Surrey in 2005 and joined Sussex in 2007 winning the Pro40 Division One title in 2008, and a one-day double in 2009, when the Sharks retained their Pro40 title and were also victorious in the Twenty20 Cup.
In 2009 he rejoined Surrey as their youngest captain in 138 years and led the side to both the CB40 title and promotion to the First Division of the County Championship.
Following the death of his close friend and Surrey team-mate Tom Maynard in 2012, he decided to return to Sussex, signing a three-year deal.
He cited Maynard's death as the motive behind his return to Sussex.
Speaking at the time he said: "A large part of it was there were many memories of Tom there. It was always going to be tough."

Sussex's professional cricket manager Mark Robinson said: "We're really sorry that Rory has had to retire from the game. He has always worked incredibly hard during his time at Sussex and has been a popular member of the club with players and staff alike.
"All we can do at this point is to wish him all the best for the next chapter in his life and we look forward to seeing him around the ground in a more social capacity for many years to come."
