Former Chiefs and Blues backline utility Gareth Anscombe will earn his first start for Wales in their pool A-deciding World Cup match against Australia this weekend at Twickenham.
Despite not being in the initial squad as he was carrying an ankle injury, he joined the side along with James Hook when Scott Williams and Hallam Amos went down.
He'll start at fullback in one of six changes made to the Welsh team, which includes George North moving in from the wing to centre.
Wales will also hand a start to Justin Tipuric at openside flanker, pushing skipper Sam Warburton to blindside to mirror the Australian style of breakdown play.
Anscombe made his international debut against Ireland in August in Cardiff, having joined the Cardiff Blues last year in pursuit of a test call-up.
Coach Warren Gatland has faith that Anscombe can take on the fullback role in a test environment.
"Matthew Morgan got a knock last week so he wasn't able to do full contact until later this week," Gatland explained. "Gareth's played a lot at fullback, experienced at Super Rugby...two years ago played the Super Rugby final for the Chiefs at fullback. I like the mix of the backline. They've trained exceptionally well this week."
"He's just [a] cool head, brings a confidence and assurance, speaks well and has that pedigree of playing at the top level as well."
Gatland conceded it could spring a surprise on Australia.
"It's nice to have someone with that sort of that experience coming into the side and someone a little bit different that they potentially weren't preparing for."
Anscombe said it's been a rollercoaster month.
"Gats spoke to me last week and said there could be a chance this weekend for a run, really excited and can't wait for Saturday arvo".
Anscombe made his name as a number 10 before developing into more of a utility and acknowledges first five is his preferred position.
"I started playing a bit of 15 [at the Chiefs] when we had Aaron Cruden playing 10. Hopefully I can jump in at first receiver every now and then."
Anscombe will match up against Israel Folau, who has been cleared to start for the Wallabies after overcoming an ankle injury.
"I played 15 against the Waratahs and he climbed all over me. He's an athlete and we know the dangers he possesses."
Wales will wrap their preparation with their captain's run tomorrow.
