Pocock made 112 Super Rugby appearances and scored 19 tries since his debut for the Western Force in 2006. He spent seven seasons in Perth before joining the Brumbies at the end of 2012.

While Pocock will not seek a new contract in Australian Rugby at the end of 2019, he will remain eligible for Wallabies selection via the 60-cap rule.

However a rare calf strain injury has left him sidelined for the forseeable future.

A Brumbies spokesman added: "David’s injury is unfortunately not progressing as hoped and needs further time to heal. No exact timeframe for a return to playing can be provided at this stage.

"After extensive consultation between the Brumbies and Wallabies Medical Staff along with other expert advice, it has been agreed that Pocock will not be available for Super Rugby selection in the immediate future."

Pocock said he was grateful to the club for the support over the last seven years and was looking forward to the future in Japan.

“The Brumbies have given me a home for the last seven years," said Pocock today.

"They've supported me through injury and given me the opportunity to work on my game and my leadership as part of an incredible group of men.

“After 13 years of professional rugby, I'm looking forward to the challenges the rest of this year holds and also thinking about what comes next.

“The Brumbies and all supporters have been very good to me since my move to Canberra in 2013. I am grateful for their support. Over the last seven years Canberra has well and truly become my home. Em and I love living here and being part of the community."
