Dan Biggar is no longer wearing a protective boot, but Wales forward coach Robin McBryde says the fly-half remains a doubt for Saturday's Six Nations clash with Scotland at the Principality Stadium.
Biggar was replaced after 20 minutes of last weekend's 16-16 draw against Ireland after taking a knock at kick-off when he rushed to collect the ball.
Wales released a statement on Tuesday confirming Biggar was still in contention to face Vern Cotter's men.
The 26-year-old is now out of his protective boot, but McBryde says he did not train on Wednesday and his availability remains touch and go.
"Dan is out of the boot and working around the clock with the medics," he said. "There are a few bruised and battered bodies, which is why we've delayed the team announcement.
"Dan has only just come out of the boot so it would be pushing things a bit. I do remember Dan Lydiate at the 2011 World Cup when it was a case of waking him up every two hours to ice his ankle. We've seen it happen before.
"Everyone is aware of the strengths he possesses with his kicking game and competing in the air."
Replacement Rhys Priestland performed well in Biggar's absence and McBryde insists there would be no qualms about turning to the Bath number 10.
"Rhys is a different player, but he proved he's as good as anyone kicking under pressure and for points," he added. "It was a difficult wind, but he coped with it.
"We've got the ultimate confidence in Rhys. He's been around a while and didn't take much away from the game. Sometimes it's easier to come off the bench.
"We created a lot of opportunities and were disappointed we didn't take them, but Rhys played a big part in that."
McBryde also confirmed that Gareth Anscombe is available following his late withdrawal against Ireland with a tight hamstring.
