Wales internationals Alex Mann, Seb Davies and Jacob Beetham have recovered from injuries during the autumn break while Taulupe Faletau, out since April, has returned to training and is expected back “in the next couple of weeks”.
Head coach Matt Sherratt will assess the eight Cardiff players who were part of the Wales autumn campaign before naming his team to face Dragons.
He said: “It’s not the physical demands of being in the Wales camp, but also the mental fatigue. But it’s a derby match at home and they want to play.”
Adams knows all about the transition from international to regional set-up and spent two weeks training with Wales as part of the final stages of his recovery.
“The boys still enjoy being part of the Wales camp, win or lose,” he said.
“It’s been difficult recently, but no one can say they don’t care about playing for Wales. That’s the pinnacle for all of us.
“They’ve gone hard in every game and some of them are pretty bashed up. Any campaign is strenuous so now it’s up to us to pick their energy.”
