The Scottish champions headed into Sunday's Clydesdale Bank Premier League clash in Paisley with the events at Parkhead on Wednesday night still dominating the headlines.
Steven Whittaker, Madjid Bougherra and El-Hadji Diouf were all shown red cards, while assistant manager Ally McCoist clashed angrily with Celtic boss Neil Lennon after the final whistle.
Walter Smith admitted he was disappointed with the reaction of some of his players and Bougherra has vowed to apologise to referee Calum Murray for his own behaviour.
But, as far as Weir is concerned, there should be no concerns overall about Rangers' discipline, as he believes they have demonstrated in recent seasons.
He said: "I disagree with people questioning our discipline. I don't think there is a problem. Anything that happened the other night, was all debatable. You could argue either way on any of the decisions.
"So if you want to say our discipline is a problem then look over the course of the last few seasons since the gaffer has been back here and it's never been an issue. I don't see it being an issue now."
