When Ireland and Scotland met in Dublin last March, the Scots battled their way to a 23-20 victory with number 8 Johnnie Beattie scoring a try and out-half Dan Parks kicking 18 points - five penalties and a drop goal.
Ireland, who were 14-7 down at half-time, had tries in each half from Brian O'Driscoll and Tommy Bowe, but it was Scotland's day.
At Murrayfield in 2009, Jamie Heaslip crossed the home whitewash and Ronan O'Gara kicked 17 points in a hard-fought 22-15 triumph for Declan Kidney's men. It was the fourth leg of a memorable Grand Slam run.
We will have live text commentary of Ireland's third match in the 2011 Championship direct from Edinburgh, with Bowe, O'Gara and Eoin Reddan coming in as the three changes in personnel from the French game.
