Wales head coach Ioan Cunningham has made one personnel change and two positional switches for Saturday's second Six Nations game in Scotland.

Sioned Harries is the one new face from the five-try win over Ireland, coming in at number eight.

Bethan Lewis switches to blindside flanker to make way for Harries.

"This team deserves the opportunity to build on the performance against Ireland for what we know will be a tough challenge away in Scotland," said Cunningham.

"We have been forced into one change due to Gwen Crabb's injury and the coaches, players and staff are all incredibly disappointed for her after she worked so hard to get back on the field.

"Gwen will get all the support she needs from us and I know she will be back."

Crabb was forced to leave the field after just six minutes with her side already 5-0 ahead and was replaced by 70-cap Harries as Wales cruised to a comfortable bonus-point win over Ireland in front of a record home crowd of 4,962.

Scrum-half Keira Bevan, who scored Wales' second try last Saturday, will win her 50th cap in Edinburgh as Cunningham sticks with an unchanged back division.

"While it was one of the best performances we have produced as a team in Cardiff, there are plenty of areas to improve on," he added.

"We have worked on those facets all week.

"The bonus-point win showed we can score tries and that is one of the areas we have targeted to improve on in this campaign.

"To score those tries will give us real confidence in the way we want to play and attack."

Lock Natalia John replaces Harries on the bench with hooker Carys Phillips and prop Cara Hope joining the replacements in place of Kat Evans and prop Caryl Thomas.

Scotland began their Six Nations campaign with a humbling 58-7 defeat by England in Newcastle - their 10th successive loss.
