Burton goalkeeper Stuart Tomlinson has been forced to call time on his playing career due to a knee injury, aged just 28.
Tomlinson, who joined the Brewers for a second spell in 2012, suffered a posterior cruciate ligament last October and, despite only being out for three months, the effects of the problem, which includes scar tissue and a tear in the anterior cruciate ligament, mean the keeper has been advised to retire.
He told the club's official website: "It's very disappointing as I was looking forward to coming back for pre-season training but with the prognosis and list of serious injuries I have had, I have to look after my long-term health.
"I'll miss being involved at Burton and have very much enjoyed my time here but I'll now explore options outside of football and look forward to making a new start in a different capacity.
"I would really like to thank the staff at Burton Albion from the manager Gary Rowett, assistant Kevin Summerfield and Kev Poole who have all helped me massively.
"The lads were awesome and that team spirit is probably what got us on a good run last season. I wish them all the best for the forthcoming season."
Boss Gary Rowett added: "Tomo was excellent for us last season and an integral part of the team.
"His retirement is naturally sad news however I have no doubt that he will succeed in whatever he decides to do next and we wish him all the very best for the future."
Tomlinson retires having made over 150 appearances in a 10-year career which began at Crewe and took in spells at Barrow and Port Vale.
