Martyn Williams is just one hurdle away from winning a dramatic 50th Wales cap in the RBS 6 Nations opener against England on Saturday.
Last weekend the Cardiff Blues flanker had been all but ruled out of the Millennium Stadium clash with a neck injury.
Also without vice-captain Colin Charvis because of a foot problem, Wales faced the prospect of pitching uncapped 21-year-old Neath-Swansea Ospreys openside Richie Pugh into the crucial encounter.
But, in the last 48 hours, Williams' recovery appears to have saved the Wales management from taking a huge gamble with the untried Pugh.
Williams came through a contact session yesterday and if he emerged unscathed from a defence training on Tuesday then coach Mike Ruddock is almost certain to include the 29-year-old in his starting line-up.
"I came through yesterday's session with no ill-effects and hopefully I'll come through today's defence session and be available for selection," confirmed Williams, who had suffered a disc problem in his neck following a training injury.
"Initially when I had the diagnosis it was a case of trying to get fit for the Italy game next week, but fortunately my recovery has been a lot quicker than we all hoped.
"I haven't started a game since January 1 and would have preferred to have a couple of games in the lead-up to this, but the good thing with the injury is that I have kept up my fitness levels.
"I feel quite fresh and I just can't wait to play again."
If selected Williams, who is likely to join Dafydd Jones (blindside) and Michael Owen (number eight) in Wales' back row, is expecting a torrid time from an England loose forward trio of Lewis Moody, Joe Worsley and Andy Hazell.
"They are three top-class players, especially Worsley and Moody. They have been there and done it," said Williams.
"They were back-ups behind Richard Hill, Neil Back and Lawrence Dallaglio but now they have come forward and proved what good players they are. There are not weaknesses there."
Wales' only other injury concern four days before the long-awaited clash is centre Sonny Parker, who is suffering from a trapped nerve in his neck. Like Williams, Parker was hoping to prove his fitness in Tuesday's training session with defence coach Clive Griffiths.
Parker is likely to partner Gavin Henson in the centre with Tom Shanklin picked on the wing. But if Parker is ruled out Shanklin would almost certainly move into the centre with Hal Luscombe favourite to be drafted on to the wing.
Meanwhile, Wales have suffered a setback in their bid to get Charvis fit for the next two games in the championship against Italy and France. His foot injury is worse than was first feared after it was discovered a piece of bone had splintered.
Charvis, capped 75 times, cannot even drive a car at present and the prospects of him being fit in the next fortnight to three weeks are rated as slim.
"He has only an outside chance of making the game in France," said Wales physiotherapist Mark Davies.
