Celtic manager Neil Lennon has called for transparency in the Scottish disciplinary procedure after Rangers 'keeper Allan McGregor was banned following an anonymous complaint.
McGregor will be banned for Saturday's game against Motherwell after being found guilty of violent conduct in the game against Aberdeen almost three weeks ago.
At the time, none of the match officials on duty noticed his attempted kick at Dons striker Chris Maguire, but following an anonymous tip-off the SFA decided to take action.
Lennon, though, would like the veil of anonymity to be removed in these situations.
"Absolutely," he said, when asked if the complainant should be known.
"If there was somebody making a complaint against one of my players I would like to know who was making the complaint?
"Does anyone know who it is?
"You are under the spotlight more when you are at the Old Firm and our games are televised more than the other teams so it would be a concern, yes.
"I think it also happened to Glenn Loovens a year or two ago in an Old Firm game. But it's something that we wouldn't look for our players to do in the first place.
"They know we have a level of discipline and code of conduct that we want to adhere too so it would be a concern if one my players did something like that.
"The most important thing for us, especially in Old Firm games, is to try and keep 11 players on the pitch.
"It's very difficult, it's an emotional game and emotions run highly during the 90 minutes."
Meanwhile, Shaun Maloney is emerging as a real candidate for the captaincy following the news that Scott Brown will be out for 10 weeks.
His team-mate, Swedish 'keeper Daniel Majstorovic has acted as a stand-in but it would appear Lennon wants to give the responsibility to a Scotsman.
"There are a couple of players in mind and we will discuss it over the next couple of days," he added.
"Daniel was stand-in captain against Inverness and he will be a candidate ass will Shaun Maloney.
"Shaun has been here a long time and showed a great level of maturity and consistency in his performance and is one of the players that players respect.
"You don't have to be vocal as a captain to set a good example.
"I think Shaun's performances this season, and the way he handles himself on and off the field, have merited him being in the running as a potential captain."
