Leicester Tigers centre Anthony Allen has been forced to retire at the age of 28 due to regular knee problems.
The 28-year-old, who made 11 appearances in his final season, joined Leicester from Gloucester in 2009 before going on to make 124 appearances.
"It is very disappointing for any professional when they realise they have reached the end of their playing career and I obviously did not expect to play my last game at such a young age, but it is something I have had to come to terms with after rehabbing a knee problem for much of last season," Allen told Leicester's official website.
"I've played alongside and against so many great players, I played in five Premiership finals with Gloucester and Leicester, played for my country and have shared in many massive occasions in 10 years as a player.
"I'd like to thank the Tigers for their support throughout this process and also thank my family and friends for all their support throughout my career, through the good times and bad. Last but not least, all the supporters at both Gloucester and Leicester Tigers have always been amazing to me and I will hugely miss running out on to the pitch every weekend."
Allen has two England caps.
