Scrum-halves Chris Leck and Alex Black have signed new contracts with Edinburgh.
The pair, two of head coach Michael Bradley's first signings last summer, have signed two-year deals with the Murrayfield side.
Leck joined from Sale Sharks, with Black coming from Leeds Carnegie.
Bradley said: "Their work ethic and professionalism has been exceptional and they deserve this chance to further their careers at the club."
And he added: "Both players have worked very hard this year, have been extremely professional and patient for their chances to play and have performed well when those opportunities have come their way.
"We're delighted that they're staying on."
Leck has featured in 11 matches for Edinburgh this term, while Black has made three appearances in his first season as a professional.
