David Callam has committed to Edinburgh Rugby by re-signing for next season on a two year deal.
The number eights performances this season, his third with the club, earned him an international call-up last November, when he came off the bench in Scotland's autumn test against Romania.
He went on to score a try the following week against the Pacific Islanders before making his first start against Australia. He has since started all three Six Nations matches for Scotland.
"It is great news that we have re-signed a player of David's caliber," said Head coach Lynn Howells.
"It shows Edinburgh will be able to compete at the highest level in future with players of David's quality re-signing for the club and demonstrates our intent to secure the top Scottish rugby players."
Executive Chairman of Edinburgh Rugby, Alex Carruthers added: "I'm delighted that David has committed to the club. He has had a great season with Edinburgh culminating in him being capped for Scotland in the autumn, and his new contract recognises his achievement. We were determined to retain a player of his stature, and so are pleased to have fought off competition from other clubs to keep David in Scotland."
