All four played in Wales' 24-6 victory over Tonga on Friday night and will be straight into the selection mix for Tuesday, although it is highly unlikely any will feature in the First Test at Eden Park. Their defense was generally sound, though winger Cooper Vuna and scrumhalf Sonatane Takulua made risky breaks for Tonga in the second half.
It was a match highlighted by bone-jarring tackles as Wales took a battering from a determined Tonga side on their way to maintaining their unbeaten record against the Pacific islanders after eight Tests.
Davies, Dacey, Hill and Francis will be big misses for McBryde, but in captain Jamie Roberts and fellow centre Scott Williams, Wales should have enough to win.

"Conditions weren't easy, especially in the second half, I think the lads assessed the risk well in the rain and our kicking was pretty good".
The match had been moved from Nuku'alofa because of concerns about the state of the pitch.
"We have said all along that we need to give ourselves the best chance of winning the Test Series and that could potentially involve calling up players".

Tonga relished the physicality, and delighted in sending a stream of ball-carriers charging upfield as far as they could.
Cuthbert was risky at times, going close to scoring when Wales spread the ball to his right wing in the third minute before being driven into touch in the tackle of prop Latu Talakai.
Flyhalf Davies added a penalty, but had two other attempts hit the post while Tonga scrumhalf Takulua kept the scoreline close with a 23rd minute penalty.
But he was finally rewarded for his sharp play on the right wing with a try in the 19th minute after being put into space by Wales' New Zealand-born fullback Gareth Anscombe. Referee Nick Brian could not see the grounding but awarded a penalty try for the Tonga collapse.More news: Sarfaraz vows to play 'attacking cricket' in clash against India
