Former Welsh and British & Irish Lions Center Jamie Roberts said “the time was right” to cut his boots on Tuesday.
Roberts, 35, has made 97 tests in his own country and on the touring side after making his international debut in 2008.
He won the Six Nations Grand Slam in his first test season and four years later, and was an important part of Lions’ successful series victory in Australia in 2013.
“I feel the time is right,” Roberts said on social media.
“At the end of my professional career, I’m retiring with great gratitude for what sports have given me,” he added.
Roberts played in five countries. His team included Racing 92 in France, Stormers in South Africa, Bath in England, Waratas in Australia, and his hometown Cardiff, where he came as an academy player.
Roberts combined his career in this field with a degree in medicine at Cardiff University and a master’s degree in Cambridge University.
“I truly cherish that sports have given me the opportunity to travel the world and broaden my horizons beyond Wales through tours and club movements,” he said.
“It was difficult to take those steps to challenge myself outside my comfort zone, but it provided the pressure I longed for.
“The pressure to challenge ourselves beyond the game has permeated the lecture rooms and wards,” he added.
He made his final test appearance in 2017 and finished his career at Waratas at this season’s Super Rugby Pacific.
“There is no doubt that he will continue to play sports after retirement,” he said.
“I understand everything, but it will be primarily in broadcasting capabilities,” he added.
