Scarlets wing Mark Jones replaces the injured Hal Luscombe

Jones reclaims the right wing berth after Hal Luscombe was injured in last week's 19-9 home loss to Ireland.

"Hal injured his knee and Mark's return to full fitness has come at just at the right time for us," Jenkins said.

"We've said 'same again' to most of the backline and given them the chance to add a more clinical edge."

Jones is the only change to the backline, although Cardiff Blues centre Tom Shanklin has recovered from a thigh strain to be named on the bench.

He replaces rookie back Aled Brew, who came on as a late replacement against the Irish to win his first cap, while Ospreys wing Shane Williams is ruled out with a stomach bug.

In the forwards we are blessed with an abundance of talent Wales coach Gareth Jenkins

The pack shows more tinkering, with a change to both prop positions and another at lock.

"In the forwards we are blessed with an abundance of talent at prop and we have gone for both Adam and Duncan Jones," Jenkins added.

"It will give us the kind of impetus and freshness we will require in Scotland in light of the six-day turnaround before this fixture.

"Chris Horsman and Gethin Jenkins both did their jobs well last weekend, but we are lucky to be able to utilise the strength in depth we have in their respective areas.

"In the second row Ian Gough also gives way to a fresher Rob Sidoli in another selection choice which is testimony to the talent available in this squad."
