Ali Price will replace Greig Laidlaw at scrum-half for Scotland against Wales in the Six Nations.

Head coach Gregor Townsend has made four changes to his starting line-up as the Scots look to get their campaign back on track following back-to-back defeats.

A key alteration comes at scrum-half, where Glasgow star Price takes the spot of national team stalwart Laidlaw.

Meanwhile, Racing 92 stand-off Finn Russell returns after missing the loss to France due to concussion protocol.

Russel's return means Peter Horne moves one place outfield to inside-centre, with Sam Johnson dropping out.

Edinburgh prop William Nel is also back to bolster Townsend's side after overcoming a calf injury.

Darcy Graham, the Edinburgh wing, has been handed his first Scotland start for the visit of the current Six Nations leaders as Sean Maitland is sidelined.

The fixture will also see Warriors duo Jonny Gray and Tommy Seymour reach a half-century of appearances for their country.

Townsend paid tribute to the pair, who he previously coached during his stint in charge at Scotstoun.

He said: "Tommy has started all his games and has an impressive try-scoring record, which is fundamental element of the game for a winger.

"As well as his finishing ability, his excellent work-rate off-the-ball and outstanding aerial skills have been the key reasons why he's reached a half century of appearances for Scotland.

"Jonny is an exceptional player who came through as a young man and, by becoming the second-youngest player to win 50 caps, shows just how well he's played in that relatively short time.

"He has a phenomenal work rate, is a very accurate tackler and takes real pride in helping the team prepare, as well as continually looking for ways to improve his own game."
