Dublin - Ireland and Munster fullback Felix Jones has been forced to retire from rugby at the age of 28 after sustaining a neck injury against Glasgow earlier this month.
"It is still unthinkable to believe I will never play another game of rugby," he said in a statement on Wednesday. "To accept I will not play with my team mates again is beyond upsetting."
Jones made 13 appearances for Ireland, playing his final game against Wales in a World Cup warm-up in August. He was part of the 2015 Six Nations-winning squad.
Earlier this year former Ireland captain Paul O'Connell called Jones "one of the greatest players that has ever played for Munster".
