Edinburgh duo Greig Tonks and Roddy Grant have agreed contract extensions with the Murrayfield Pro12 club.
Tonks, 25, who can play at full-back or fly-half, won his third Scotland cap in last weekend's loss to England.
Botswana-born back row Grant, 28, has been with Edinburgh since 2009 and was captain for the 2010-11 season.
Grant's new deal runs until May 2016, with Tonks, who joined from Northampton Saints in 2012, signing terms until 2017.
"I've been at Edinburgh for three seasons now and I feel as though we have a good group of young guys coming through, keen to play for the club," said Tonks.
"The high points of my time with the club so far have been this season's run in Europe - particularly the away win in Bordeaux - and last season's win over Gloucester. Of course, beating Glasgow to win the 1872 Cup and winning Player's Player of the Year are up there too.
"I'm lucky to be around such a good group of people, there's a good team atmosphere.
"I genuinely believe Edinburgh will be going places in the next few years."
Grant has played his entire professional career for Edinburgh and will continue to do so for at least another season.
He said: "I've agreed to stay on for a year because I strongly believe in Alan [Solomons] and Stevie [Scott] and going forward with this great group of players at the club."
