Edinburgh have signed Argentina back-row forward Tomas Leonardi on a three-month contract from South African outfit Southern Kings.
The 26-year-old arrives ahead of Thursday's Heineken Cup squad registration deadline.
Edinburgh head coach Alan Solomons worked with Leonardi during his time as Kings director of rugby.
"Tomas is a physical player, who is equally comfortable at number eight or on the blindside flank," said Solomons.
Leonardi began his professional career in 2010 for Argentina's high performance squad, the Pampas XV, in South Africa's Vodacom Cup.
He went on to establish himself in the national side, earning 18 caps to date, before joining Kings in 2013.
Solomons added: "He's an experienced international who is capable of adding value the squad."
