Ireland's John Lacey will referee his first ever RBS 6 Nations match in February, while Alain Rolland is also included in the Elite Panel in what is his last season.
In the early hours of Thursday morning last week, Allen Clarke's Ireland 'A' side began their 2008 Churchill Cup campaign with a 46-9 victory over the USA.
But their bid for a place in the final faltered in Toronto last Saturday as they suffered a 34-12 defeat to England Saxons.
Nonetheless, the Irish can still end the tournament on a high by beating Argentina 'A' on finals day at Toyota Park in Chicago. Victory would see them lift the Churchill Cup Plate title for the third successive year.
So plug in the laptop or turn on the PC and enjoy Saturday's game live on IrishRugby.ie with thanks to O2, sponsors of MatchDay Live. Kick-off is at 11.45am Chicago time/5.45pm Irish time.
