Toulouse have completed the signing of Bayonne tighthead Gert Muller for next season on a one-year deal.
The 29-year-old will follow the same path as former All Black Neemia Tialata who swapped Bayonne for Toulouse last season.
Bayonne were relegated from the Top 14 on the final day of the season, and have already lost the likes of Charles Ollivon and David Roumieu for 2015/2016.
Muller played for the Lions when he was in South Africa before arriving in France with Agen in 2010.
He joined Bayonne last year and played 22 games, starting 17 in the Top 14.
