Rangers chairman John McClelland has vowed to root out the racist minority who brought shame on the club at Parkhead on Saturday.
Some racist abuse was heard from a few Gers fans when Bobo Balde and Momo Sylla had possession during the Hoops' 1-0 win.
Now McClelland is determined such behaviour will not be tolerated among Ibrox fans in the future.
He said: "I do not condone this kind of behaviour, I deplore it. There was such a crescendo during Saturday's match and although I thought I heard noises of this kind I can't be 100 per cent sure. However, if it did happen, it is unacceptable.
"It is a difficult problem to deal with because I know it must only be a small minority but we will do everything we can to make sure the message gets across to our fans," he said.
"We do not want people who come to games to indulge in racist behaviour like this".
