JOE SCHMIDT has completed a forensic review of Wayne Barnes' display at the Millennium Stadium last weekend and is awaiting a response from World Rugby's head of referees Joel Judge.
Ireland remain unhappy at a perceived lack of consistency in the English official's decisions around the breakdown between the first and second halves of their 23-16 defeat to Wales, while they are confused over his last-gasp call to award a penalty against Cian Healy at the last scrum when the Irish pack had won the ball against the head.
"We have given our thoughts to Wayne, we've done that and we haven't had any feedback and it's probably best to wait until we've had that feedback before commenting," forwards coach Simon Easterby said.
"All I can say is I think we prepared really well for Wales, Greg Feek did a great job preparing the scrum; both the guys who started and the guys who came off the bench. We felt like we put ourselves in a strong position at times, but we'll have to wait and see what the feedback is from our report before we make too many comments and hopefully that will come within the week."
Ireland have had Barnes twice during this year's Six Nations and both times they conceded more than 10 penalties, well above their average under Schmidt.
Asked where they could improve against Scotland, Easterby highlighted the team's discipline.
"We pride ourselves as a team, and have done for a long time on making sure that we don't give sides that type of momentum that we gave the Welsh," he said. "Playing away from home, you give a side, three, six, nine, 12 points then things start to pressure you and you start to put a bit of pressure on yourselves.
"We were very well prepared for the referee. Maybe (when) we had some opportunities in the second-half we weren't afforded some of that consistency. And as the game developed we felt like we had some momentum and we didn't quite get the same decisions at times.
"That being said we can still be far better at certain things in our control. Unfortunately we can't control the one guy out there."
"There are probably three or four elements of our game that we didn't quite get to our standard on and at that highest level you lose out on two or three lineouts, you give away two or three penalties, then it's always going to be a difficult game."
