Former Wales lock Quinnell injured the discs in his neck when coming on as substitute for Cardiff against Glasgow two weeks ago, sustaining the damage in contact.

He visited a specialist this week who confirmed his playing days are over, leaving the 30-year-old to reflect on life as a rugby spectator.

He said: "Obviously I'm really disappointed I'm never going to play again whether professionally or even a fun game.

"The consultant has told me I could be one hit away from a wheelchair and that really hits home how lucky I have been.

"Hopefully Ill be able to continue to play other sports such as golf and squash, as well as lead a normal life.

"I'd like to thank everybody who has been involved with me in my career.

"I've had a total of six years in the capital with many ups and downs in that time, but I've enjoyed every minute.

"I can't think of a better place to have finished my career than here. I'd like to thank all the Blues faithful who have cheered me on.

"It's a very sad time for me and it's going to be hard to adjust to life without rugby. Once again I'd just like to thank everybody."

Quinnell won 32 caps with Wales after making his international debut as a flanker against Fiji in 1995.

He was a member of the 1999 World Cup squad, played in the famous 32-31 victory over England at Wembley and was an ever-present during the 10-match winning streak under Graham Henry.

His club career started at Llanelli and included stints with Richmond, Saracens and Worcester before he signed up for his second and final spell with Cardiff in 2003.
