Rhys Williams has rallied Wales for the final assault in their fearless Grand Slam mission, by declaring: "We want to create our own history."
The Cardiff Blues wing, though, could yet suffer injury heartache by missing out on Welsh rugby's biggest day since 1978.
Wales will secure a championship clean sweep, the Triple Crown and 2005 RBS 6 Nations title if they beat Ireland in Cardiff on Saturday.
But Williams, who was not born when Wales last enjoyed Grand Slam glory 27 years ago, is battling to overcome a calf muscle problem.
Hooker Mefin Davies (leg) and replacement wing Hal Luscombe (hamstring) are also receiving treatment, with coach Mike Ruddock putting back his scheduled team announcement 24 hours.
Williams admits Saturday's Millennium Stadium showdown with the Irish is one game he would not want to miss, and is doing everything possible in his fitness quest.
"I've been up every two hours day and night, icing the injury since the game, just to give it the best chance. It is still being monitored, and I would hope to be able to train Wednesday or Thursday," he said.
"As far as Saturday is concerned, it is the pinnacle for us now, but we are relaxed and looking forward to it. As a team, I think it is evident that we play best when we are relaxed.
"We are trying to distance ourselves from all the hype, and we realise that we have got a lot to work on from the Scotland game - first-half performance as well as second half. We were allowed to get away with our mistakes," added Williams, following the record-breaking 46-22 Murrayfield triumph when he scored two of Wales' six tries.
"As a squad, we realise that we've put so much hard work in over the last few years, and to let ourselves down now would be a major slip-up. We are looking forward to the game like never before.
"We want to create our own history, and it would be great to create some on Saturday. But we've also said that we are not happy with just creating that history, we want it to continue."
England flanker James Haskell insists he will be pushing as hard as possible to be back from a toe injury in time to make his case for a spot in Eddie Jones' side looking to defend their RBS 6 Nations title next year.
