Top 14 leaders, Toulouse, have signed Argentina back Juan Cruz Mallia on a 10-month deal, confirmed president Didier Lacroix on Tuesday.
The 24-year-old made a June 2018 Test debut versus Scotland at Resistencia and was part of the Los Pumas squad at the 2019 World Cup under Mario Ledesma.
"He's a player who can play anywhere in the backs, who has performed well with Argentina," Lacroix said.
"He comes to supplement a backline where we have sometimes been very tight. He could stay at the club for longer if the two parties wish," he added.
Mallia featured once at the 2019 Rugby World Cup and could make his club debut for January 31's trip to second-placed La Rochelle.
The club also confirmed that fly-half Romain Ntamack is out for a month with a broken jaw and winger Tauzin will be sidelined until May with a knee injury.
