Biggar had to be taken off the game at Aviva stadium early owing to an ankle injury having played less than 20 minutes. Rhys Priestland deputized for the burly fly-half in that match but Biggar recovered sufficiently from the knock to start against Scotland at the Principality Stadium in Cardiff over the weekend.
Captain Sam Warburton will continue at blindside while Justin Tipuric retains his place in the starting team. The Ospreys openside was reasonably impressive against the Irish which should have been the strongest reason for him keeping Dan Lydiate out.
Taulupe Faletau celebrates his try against Ireland with another chance to start at number eight while Jonathan Davies wins his 50th cap. Jamie Roberts, another impressive performer from the previous match, keeps his place in the centre. Roberts made 21 tackles in a bruising encounter against Ireland and would be key once more for Warburton on the field.
Gareth Anscombe returns to the match-day 23 after missing the earlier clash because of a hamstring strain. This means a move out of the 23 for Alex Cuthbert. But, the biggest news coming out was the fitness of Biggar.
Wales were unlucky not to win full points with a late penalty from Jonathan Sexton earning the share of spoils for Ireland. Gatland would be impressed with the way his squad came back into the game after being 0-13 down early in the first half. But, he would be disappointed with having to share the points.
Biggar would be expected to play a stellar role for Wales as they look to iron out their deficiencies and go for a win against Scotland. Will his hamstring allow him to play out the full game? Watch out for the early signs!
