Wales are hopeful fly-half Dan Biggar will be fit to face France in the Six Nations on Saturday.
Biggar suffered concussion during their 24-14 defeat to Ireland in Dublin.
The Grand Slam champions are struggling at 10 after Owen Williams was ruled out of the tournament with a hamstring injury.
However, Wales assistant coach Jonathan Humphreys hopes Biggar will be fit to face France in Cardiff.
He said: "Dan Biggar's good. He's taking part in full training. He's hopefully going to carry on and pass his protocols.
"Fingers crossed he'll be ready."
Meanwhile, winger Josh Adams is fit and has returned to training after suffering a hip injury in Dublin.
Head coach Wayne Pivac has also called-up Cardiff Blues back Hallam Amos to replace Owen Lane, who has also been ruled out of the remainder of the campaign.
'France will hit and chase and cheat'
Wales front row Wyn Jones has raised tensions ahead of the game by suggesting that the French scrum will "hit and chase and cheat" at the Principality Stadium.
France are targeting a first Six Nations win on Welsh soil since 2010, and Jones has suggested the leaders will go to any lengths necessary to maintain their winning start.
"They'll be a big pack, but probably ill-disciplined with that, especially at scrum time," Jones said.
"We know they will hit and chase and cheat. That's something we are fully aware of and something we've got to combat on the day.
"They will look to push early, they'll look to mess about at scrum time. That's something we've looked at. We will just concentrate on ourselves."
Asked for his general view on scrums, Jones added: "In any aspect of the game, all you want is consistency, and maybe some calls are frustrating, but you've just got to play what's in front of you.
"The scrum is constantly evolving. I think we're all on the same page - that's the main thing.
"We just keep evolving our scrum. We show positive pictures. That's the kind of scrum we want. We want to be positive, a 'no cheating' mentality."
