Europe's governing body have instigated proceedings against the Scotland global for tying a scarf around a Windsor Park goalpost after Friday's highly-charged second qualifying round, first leg win over Linfield.
Following last Friday's 2-0 defeat in the first leg, he says believes his players didn't get enough praise for their efforts. It's an incident I don't really want to go overboard on, to be honest.
"Sometimes no matter what things you do as a club, you can't prevent a few idiots who follow the club".
"It is hugely disappointing as the manager of the club, as we tried to make it about what happens on the pitch".
The two teams meet again tomorrow evening for the second-leg at what will be a full Celtic Park.
"It's hugely important tomorrow night that that thousand or so supporters who are going to be there behave in an impeccable manner, enjoy the game and the occasion and we come away talking about hopefully another positive Linfield performance".
He was forced to remove objects from the field including coins and a bottle, and was subsequently booked by Spanish referee Alejandro Hernandez for time-wasting.
The European governing body has also instigated disciplinary action against Linfield over their supporters' behaviour, and Celtic for their yellow card count.
The Hoops on the other hand, had received five cards during the game, and they are now being charged with the improper conduct of the team, while striker Leigh Griffiths has been accused of provoking the home fans as he tied up a scarf of his club to the woodwork on the stadium.
Healy concedes it will be the biggest game most of his side have played in but is looking for another disciplined show against the Scottish treble winners.
"We'll just wait and see what the hearing result is on Thursday".
'It could mean he misses a Champions League qualification game, which is a huge game for the club and it's a huge game for him considering he wants to be available and play all the time'. We're a team that's very disciplined in how we work and we'll remain being that.
