Gareth Llewellyn will Neil Jenkins to make a record-breaking 88th Wales appearance when he lines up in the second row against Argentina at Tucuman.
The 35-year-old has overcome a twisted ankle to line up alongside debut-making Newport Gwent Dragons flanker Jason Forster and his South African-born team-mate and wing Hal Luscombe, who is making his second Wales appearance.
However, for Llewellyn, who earned his first cap from Neath as a 19-year-old against the 1989 New Zealand All Blacks, beating goal-kicking ace Jenkins appearance mark will pass without fuss.
The 35-year-old said: Its something I will look back upon when I am older and appreciate more.
But at the moment I am just enjoying being part of the squad and playing for Wales - and that is why Im here.
Im not hanging around to break records. I think I can still contribute to the national cause and think I am good enough to be involved.
If I was here just to hang on for a few more caps, Id be doing everyone a disservice.
Wales coach Mike Ruddock has no qualms about continuing to field Llewellyn, despite his age.
Ruddock said: Gareths recent performances have been an example to all the younger players.
He showed against the Barbarians that he still has the legs at this level - and if hes good enough for Test rugby, I have no doubt he is capable of performing at top European club, regional or provincial level.
