Argentina have secured another big name for their Super Rugby team in form of veteran loose forward Juan Manuel Leguizamón.
The former London Irish and Stade Français player will return home from French club Lyon and provide invaluable experience after ten years in Europe.
"This is another important day for Argentine rugby," said UAR President Carlos Araujo.
"Juan Manuel has been a strength of the Pumas and one of the pillars of a process that has been underway for years and that will peak in 2016 with the inclusion of Argentina in Super Rugby.
"For these reasons, it is a remarkable and very important gesture for 'Legui' to return home and sign his contract with the UAR, and is a further demonstration of his enormous commitment to the Argentine rugby."
The 32-year-old player also expressed his enthusiasm and commitment to the future of Argentine rugby.
"The priority was always to play for the Pumas and when the idea of the franchise first emerged, I was gagging to be a part of it," said Leguizamón.
"There were many things that made this decision easy. The project is amazing and I could not wait to be part of it. To play Super Rugby is extraordinary and be part of it has to do with the decision. "
Leguizamón has inked a contract from 1 January 2016 that will run until the end of the 2017 season.
