Wales captain Stephen Jones is over a knee problem and available for Saturday's Test with New Zealand.
But Gareth Thomas, who led the side in Friday's win over Canada, is a major doubt with a knee injury from the game.
Gavin Henson, a late withdrawal from the Canada match with a toe infection, is expected to be available.
The highly competitive team selection will be announced on Wednesday, but decisions on Thomas and Henson are expected to be made on Monday.
Lock Brent Cockbain is back from suspension and could challenge Ian Gough for a place, but a lack of game-time would seem to make that unlikely.
Ian Evans has impressed in the other second-row berth, but with Robert Sidoli also in form Evans' discipline problems could cost him a place.
Duncan Jones and Rhys Thomas are pushing Gethin Jenkins and Matthew Rees for starting berths, but the major selection dilemmas are in the backs.
Even if he is fit, Thomas is struggling to hold on to his place, Kevin Morgan having played full-back against Australia and the Pacific Islanders and wings Shane Williams and Mark Jones showing outstanding form.
"It doesn't look like Gareth will make it at the moment but we are trying to remain positive," said Wales coach Gareth Jenkins.
"Gareth is a key player in our environment, not just on the field but in the team environment. It would be huge if he wasn't available."
Stephen Jones will play at outside-half after recovering from the ligament problem he picked up early in the 29-29 draw with Australia.
Ceri Sweeney and James Hook could have covered him, but they are contenders for Henson's number 12 jersey, a shirt the physical and in-form Sonny Parker filled against Canada.
"It is a big decision for everybody in Wales," said Jenkins.
"We got a lot out of the Canada game. Our line-out was good; our scrum was always on top, and at times we played some brilliant rugby.
"But there were parts that were frustrating, particularly our indiscipline at the contact area.
"We conceded seven penalties for coming in off the edge. That is too many.
"We conceded five penalties on the trot in the second half. We cannot afford to do that against better opposition."
Jones was upbeat after being cleared to resume full training on Monday.
"There was no way I could play against Canada, but I'm back to full fitness now and I haven't lost any aerobic fitness because I have still been able to run in a straight line - lateral movement was the problem," said Jones.
"There's a realistic chance of us beating New Zealand. We ran them close two years ago and we want to play the Welsh way, be positive and attack from all areas.
"Against France, New Zealand were excellent, efficient and ruthless in the contact area - they turned France over if they didn't commit enough men to the breakdown.
"But we play a different way, move the ball around and will look to take the game to the All Blacks.
"We've improved every week through the autumn and take in a lot of self belief."
