Scrum-half Greig Laidlaw has inked a new two-year contract with Edinburgh.
Laidlaw has made 11 starts this season and earned a man-of-the-match award against Stade Francais in the Heineken Cup.
Skipper Mike Blair's recent injury lay-off has boosted Laidlaw's appearances tally but the 24-year-old is looking to challenge Blair on a long-term basis.
"I'm very happy to be signing for another two years. First and foremost, I want to help the team reach the play-offs and challenge for the title," said Laidlaw, who made the first of his 53 Edinburgh appearances in 2006.
"Another target is that I want to keep my place in the Edinburgh side.
"Mike has just signed a new contract as well, so I'm looking forward to the battle.
"I've been delighted with how this season has gone so far. I think I've developed massively as a player.
"I've really enjoyed my rugby and I think that has shown on the pitch. I've been pleased with some of the performances I've put in and long may that continue."
Head coach Rob Moffat feels Laidlaw can go from strength to strength after following Blair, Allan Jacobsen and Chris Paterson in extending his contract.
Moffat said: "I think Greig has really stepped up. He has played a lot more rugby for us this season and he deserves everything he has received.
"I thought Greig was outstanding against Stade Francais in our last game and we are delighted with the way he has progressed and that is largely down to the way he applies himself. Hopefully that improvement will continue.
"The fact that we have players of the quality of both Greig and Mike competing for one spot shows our squad has some depth."
