London Wasps centre Lee Thomas has been forced to retire at the age of 29 because of an ongoing Achilles problem.
He suffered the ruptured tendon last December and despite undergoing seven operations has been unable to recover.
"The decision becomes a lot easier once it is taken out of your hands but it is still very difficult to accept," Thomas, a former Wales under-21 player, told the BBC. . Wasps director of rugby Dai Young said: "It's a real shame because when he suffered the injury he was really beginning to settle into the club and starting to play some great rugby."
