Dan Biggar will be fit to face Fiji in Wales' next World Cup match after he was knocked out in the win over Australia.
The fly-half, 29, tackled Wallaby centre Samu Kerevi to save a try in the first half and suffered a concussion.
He failed a head injury assessment and was replaced by Rhys Patchell - but with eight days until Wales' next fixture the coaches are confident he will be able to return.

'He is symptom-free at the minute, and obviously just doing his protocols as you normally would,' said skills coach Neil Jenkins.
'As far as I understand, he will be ready to go by the time we play Fiji, so that's obviously good news.
'He's fine. He is pretty good around the team room.
'He is an outstanding rugby player, a world-class rugby player, so he's a huge part of our team and the way we like to play the game.
'I think we must not forget how good Rhys was when he came on, and how good a player he is as well. We are quite lucky to have the strength in depth that we have in our squad.
'We have only got two 10s, and they are both vitally important to us.'
