So how do you begin to unravel that? A game with five yellow cards and a contest-altering red, a match with 26 penalties - all ensuring that referee Frank Murphy was the dominant figure - and also an occasion with eight tries, oh and one that was disallowed too. The unfortunate thing from Ulster's point of view was that they had to absorb the sending off and the disallowed try and this after playing some sublime rugby to go 12-3 ahead in as many minutes. Andy Warwick's 30th minute red card for leading with the elbow into Ed Byrne's neck was the one that changed everything - the TMO suggesting referee Frank Murphy look for another colour rather than a potential yellow.
