Star Brumbies lock Sam Carter will leave the Super Rugby club at the end of the 2019 season for a stint in Europe.
Carter's two-year deal with Pro14 club Ulster is close to being finalised and an official announcement is imminent.
The Brumbies announced the departure of their former co-captain on Thursday through Twitter, but the post was quickly deleted.
A former Wallaby, Carter made his debut with the ACT franchise in 2011 and has played 105 games.
He last played for Australia in June 2017, having fallen out of favour with Wallabies coach Michael Cheika.

But the move abroad is expected to rule him out of calculations for the World Cup, starting in September, and leave him on 16 Wallabies caps.
Carter's move to the Belfast-based club will be full-time, compared to Brumbies teammates Christian Lealiifano and Henry Speight's short-term loans at Ulster.
His departure will leave the Brumbies short on locks in 2020, with fellow big man Rory Arnold also set to move overseas and link up with French club Toulouse.
