Danny Lydiate has recovered from injury and is fit to join Toby Faletau in the Wales back row for this Sunday’s RBS 6 Nations match at Millennium Stadium.
Sam Warburton has also been declared fit to captain the side.
Gethin Jenkins and Dan Lydiate have both recovered from injury to start against the Scots and Ryan Jones, who featured in the back row in Wales' 23- 21 opening round win over Ireland in Dublin last weekend, moves to lock.
"Dan's return from injury is timely and Ryan's versatility allows us to cover for Bradley with minimum disruption, with Lou Reed also giving us an extra option from the bench,” said Wales head coach Gatland.
"We cannot afford to underestimate Scotland, the amount of possession and territory they had against England last weekend meant that they should have won the game and they will come to the Millennium Stadium buoyed by that knowledge."
Wales assistant coach (backs) Rob Howley agrees that his side must have the right approach in order to achieve victory over Scotland this weekend.
"The standards we set in Dublin where high and we want to attain that level throughout the Six Nations," said Howley.
"We are playing particularly well at the moment, and it was a pleasing performance from the backs, we were accurate and took our opportunities well.”
"The Six Nations is a magical championship and the one thing we all know is that if you don't front up in a Six Nations game you can get beaten.”
"Scotland should have beaten England at the weekend, they will be obviously disappointed and they will want to go one better, which would obviously mean winning the game, so we must be ready for them."
