Paris - French giants Toulon on Thursday signed Argentina international back-row forward Facundo Isa on a two-year deal with the transfer taking effect at the end of the season.
The 23-year-old, who has 25 caps, played one match for the triple European champions in the 2013/2014 season before heading back to Argentina.
Isa is the club's sixth new signing for next season after wingers Chris Ashton and Filipo Nakosi, fullback Hugo Bonneval, centre Semi Radradra and back-rower Raphael Lakafia.
