Springbok flyhalf Pat Lambie is poised to sign for French Top 14 side Racing 92 after negotiating an early release from his contract with South African Super Rugby franchise the Sharks.
Lambie will also be released from his contract with the Boks that will leave him free to play for Racing in the coming weeks.
Both the Sharks and the Boks are expected to make an announcement on his future later on Monday.
The 26-year-old has endured a torrid time of late with injuries, and has not featured for the Boks this year, having been unable to add to his 56 Test caps.
The emergence of youngster Curwin Bosch at the Sharks has also potentially limited his gametime at the union in the future, influencing his decision to make the move to France.
A series of concussions in recent years, the latest this May, had left Lambie on the sidelines as he battled with headaches, light sensitivity in his eyes and neck problems.
But he committed to returning to the field of play as soon as possible and after four months of rehabilitation is now close to doing so.
Lambie made his debut for the Sharks in Super Rugby in 2010 and earned his first Test cap later that year in a 23-21 victory over Ireland at Lansdowne Road.
He will still be eligible for the Boks if selected as he has passed the number of caps required for overseas players, 30, and could yet be an important part of their squad for the 2019 Rugby World Cup in Japan.
