Unlikely as it might have seemed, Ireland came within a (Argentinean) TMO's decision of losing this one, as referee Wayne Barnes went 'upstairs' to determine whether the Georgians had grounded after they'd rumbled over when just two minutes of normal time remained of a second half they'd dominated.
In fairness had the try been awarded, it would have been a travesty from the point of view that from every TV angle, there was no view of a grounding. And so it transpired.
But had the supposed 'minnows' snatched a victory - as they so very nearly did - the Irish could have had no grounds for complaint.
Ireland took the victory and the points thanks to a first half try from Rory Best and a second half one from Grivan Dempsey most to superb hands from the man who replaced Best, Jerry Flannery.
Ireland led 7-3 at the break but then conceded a try when Peter Stringer's pass to Brian O'Driscoll was intercepted by Giorgi Shkinin who raced the length of the field to score under the posts.
Delightful quick hands from Flannery put Dempsey clear for a vital try but from then on it was the Georgians who dictated and dominated matters.
In the end Ireland just about held on and afterwards O'Sullivan insisted "It was a a better performance than last week, we just met a better team."
