Morgan forced to bow out
Gloucester's twice-capped England international Olly Morgan has confirmed his retirement with immediate effect.
Morgan, 27, has not played since tearing his lateral collateral and anterior cruciate ligaments in his knee in a game against Worcester in January 2012.
The full-back has made numerous attempts to get match-fit but has now accepted that his career is over.
"It's been such a difficult decision. Even though I've had a long time to consider this moment, it doesn't make it any easier," he said on Gloucester's website.
"The frustrating element is that we've actually made so much progress with my knee.
"However, I have had to reluctantly accept that the knee would not be able to cope with the stresses of matches week in and week out, as well as regular training sessions. It would just be too much."
Morgan's England caps were won in the 2007 Six Nations against Scotland and Ireland, and he looks back on international selection as a particular highlight.
"There have been so many great moments. I've loved every minute of my time as a Gloucester player, and I represented my country. Not many people can say that," he added.
"It's disappointing that I'm not able to bow out in the way that I'd like, but I've had so many highs and made so many great friends. You can't have any regrets when you look at it like that.
"I'd like to thank my team-mates, the coaching staff, everyone who works at Kingsholm and the supporters of course. It's been a special experience.
"This particular chapter has come to an end. And it's disappointing that injury got the better of me. But that's a fact of life in modern rugby."
Morgan retires having made 131 appearances for Gloucester since his 2004 debut. He scored 30 tries.
