Munster Rugby and the IRFU have announced that Felix Jones is to retire from rugby on medical grounds.
They said: “Having most recently sustained a neck injury during the round 3 PRO12 encounter against Glasgow Warriors in Thomond Park Felix Jones has been advised to retire from rugby.”
The 28-year-old made 90 appearances since joining the province in 2009, scoring ten tries.
Jones also played 15 times for Ireland since earning his first senior cap in 2011.
Jones said he was still coming to terms with the decision.
"It is still unthinkable to believe I will never play another game of rugby,” he said in a statement. Although I have tried to round myself as an individual through education and other interests, I have always had one driving purpose in my life and that was to play rugby.
“I'm grateful I could do that in Munster. That feeling of walking out the tunnel in front of a packed Thomond Park is something I will never forget. To accept I will not play with my teammates again is beyond upsetting. I'm lucky to have played with so many great players, but rugby has given me something better and that is the people who are now life-long friends.
"I would like to thank my family and close friends for their undying support on and off the pitch. I will draw upon this over the coming weeks as the situation presents itself as a nervous yet exciting junction in my life."
Munster Head Coach Anthony Foley said "We are all hugely disappointed for Felix. He was a leading example in the way he applied himself through his commitment, work-rate and attention to detail.
"For a player to come in, embody everything that is Munster and have such a presence within the group he will be sorely missed on and off the field. We are very grateful for Felix's immense contribution over the last six years and wish him all the best for the future."
Fellow player and fans have been shocked at the news, and have expressed their sympathies to the player on the unexpected end to his rugby career.
