Dragons prop Jack Cosgrove has been forced into retirement at the age of 25 after suffering an injury to his left eye in training.
The former Scotland Under-20s loosehead only arrived at the region in the summer from Gallagher Premiership Worcester Warriors.
The Coventry-born front-rower was in his second spell at Sixways having also played for Doncaster Knights, Edinburgh and Bristol Bears.
The former Hartpury College student sustained a serious eye injury while training with the Dragons at Ystrad Mynach in October and following specialist treatment has hung up his boots on medical advice.
Cosgrove made his debut for Dragons in the Guinness PRO14 fixture with Connacht in October, after appearing in six out of eight Celtic Cup fixtures for the region during the early part of the season.
"Everyone at the Dragons wishes Jack every success in his future and he will continue to receive professional help and support from the region as he makes the transition from playing," said a statement from the region.
