* Five of Ireland's current squad - halfbacks Ronan O'Gara and Peter Stringer, forwards John Hayes and Simon Easterby, and winger Shane Horgan - made their international debuts against Scotland in 2000. The 44-22 win established a new record for a defeat of the Scots, eclipsing 1950's 21-0 success.
* Eddie O'Sullivan is gunning for a fifth straight win over the Scots, since taking to the Ireland helm in 2002.
* An Irish win on Saturday would see O'Sullivan's chalk up back-to-back Championship wins over their Celtic rivals for the first time since 1983-85.
* The emergence of the Six Nations in 2000, has really changed Irish fortunes against the Scots. Before the millennium, the men in green had lost eleven on the bounce against their northern neighbours - now, they hold a won five, lost one record since 2000.
* David Humphreys is the record points scorer in recent meetings. The Ulster fly half also hold the all-time record, having bagged 82 points in nine tests. Scotland legend Gavin Hastings - their all-time top scorer with 667 - is next best on 62. Humphreys hit a record 26 points - a try, five penalties and a conversion in 2003's 36-6 Irish win at Murrayfield - their first win in Edinburgh since 1985.
*If Brian O'Driscoll starts and touches down, it will be his fifth try in seven internationals against the Scots. Pint-sized Scotland scrum-half Roy Laidlaw - a feature in their side from 1980-88 - holds the record with six in nine games.
* The Ireland v Scotland fixture is the third most played match in international history. Saturday's meeting is the sides' 118th - the Irish have won 50 of those. Scotland v England tops the list with 121 previous clashes.
* 1885's abandoned game saw Scotland leading a try to nil. Caps were awarded for both the abandoned game and the replay two weeks later. The Scots at that stage, had already chalked up a record eleven wins in the fixture - a mark which still stands today.
* Scotland's Tasmanian-born winger William Stewart scored a record four tries in the 1913 fixture. Ireland's current captain Brian O'Driscoll grabbed a hat-trick in 2002, with Eugene Davy (1930) and Seamus Byrne (1953) also collected three tries in a single game.
