Oyonnax have continued their recruitment drive with the signing of Lyon back three player Vincent Martin.
The Toulon academy product was highly-rated as a youngster and a key part of France's age group sides.
Having initially broken into the Toulon side in 2012, he was called into the French squad to train but is still uncapped.
After an injury-disrupted season he left Toulon, having slipped down the pecking order, but he has played just five games for Lyon.
However he will follow Lyon forwards coach Olivier Azam in moving to Oyonnax, who announced the signing of Fetu'u Vainikolo earlier this week.
Martin has signed a three-year deal at Charles Mathon.
