Argentina forward Tomas Leonardi has extended his contract with Edinburgh until the end of next season.
The 26-year-old back-row joined in the autumn on a short-term deal but has impressed enough during his seven appearances to be handed an 18-month extension.
"In these three months I've done my absolute best to perform for the club and make a good impression," said Leonardi.
"Securing a longer deal eases my mind a bit and allows me to focus more on myself and plan some longer-term improvements for my game, but I'll still work as hard, day by day, to repay the coaches for the faith they've shown in me."
Edinburgh head coach Alan Solomons added: "Tomas is a physical, abrasive and hard working player and his training and performances have justified this extension.
"He's comfortable across the whole back-row and this versatility is extremely valuable to the squad.
"He's settled in the city and with the squad, and has done well in the short time he's been with the club.
"We're really pleased he's agreed to stay for another season and look forward to the value he'll continue to add in an immensely competitive area of the Edinburgh Rugby squad."
