Edinburgh have signed Argentina back-row Tomas Leonardi on a three-month contract.
Leonardi, 26, played for the Southern Kings for the 2013 Super Rugby season, and he has arrived in time to be registered for Heineken Cup.
Edinburgh Rugby head coach Alan Solomons - who worked with Leonardi during his time as Kings' director of rugby - said: "Tomas is a physical, abrasive player, who is equally comfortable at No 8 or on the blindside flank.
"He's an experienced international who is capable of adding value the squad."
Leonardi has won earning 18 Pumas caps to date.
