Scotland have made one alteration to their starting line-up for Saturday's Six Nations clash with Wales as Duncan Weir replaces Ruaridh Jackson at 10.
Weir, whose three previous caps have been won from the bench, replaces his club-mate Jackson in the pivotal position and was delighted to start.
"It's a moment I'll cherish and hopefully I can do the coaches justice for giving me the start," he told www.scottishrugby.org.
"The other change to the initial line-up from the team that defeated Ireland last month sees the 2009 British and Irish Lion, Euan Murray, return to the tighthead berth with Geoff Cross moving to the bench."
Ryan Wilson, the 23-year-old Glasgow Warriors number eight who has led his club on three occasions this season and who was captain and man of the match in Scotland A's victory over England Saxons last month, is introduced to a matchday 23 for the first time.
Wilson is named instead of David Denton who sustained a knee injury when playing for Edinburgh Rugby against Scarlets in the RaboDirect PRO12 at the weekend.
"Selection is tough just now but that's a good thing as we increase competition for places," said Scotland interim head coach Scott Johnson.
"Duncan did well when he came on against Ireland and he got some decent game time for Glasgow at the weekend. He's a talent with a really good work ethic and a thirst to improve, which I like a lot.
"Ruaridh remains a key part of our squad but he knows with Tom Heathcote proving a match-winner for Bath and kicking goals from here, there and everywhere, that he needs to up his game too.
"Geoff (Cross) was a standout against Ireland and it's up to Euan, who fronted up big time against Italy, to raise the bar again.
"Wales will be going for their fifth successive away victory in the championship and that would be a record for them but our focus is on ensuring we win the contact zone, continue to improve and make it three wins on the bounce."
