London - Newport Gwent Dragons' former Wales fullback Lee Byrne has been forced to retire due to a shoulder injury, the 34-year-old announced on Thursday.
The former British and Irish Lion, who also played for Scarlets, Ospreys and Clermont, made his international debut in 2005 and went on to make 46 appearances for Wales, with whom he won the Six Nations Grand Slam in 2008.
He joined the Dragons last year and was subsequently appointed captain, but after undergoing shoulder surgery in November, he has been obliged to call time on his career.
