Celtic manager Neil Lennon has condemned Alfredo Morelos and Ryan Kent for their respective reactions to Scott Brown, BBC Sport reports.
Both players were involved in altercations with the Celtic captain but one was punished and the other was not seen.
Bobby Madden showed a straight red card to Alfredo Morelos in the first half after the hot-headed Colombian elbowed Brown.
But after Celtic’s late winner, replays showed that Kent knocked Brown to the floor after a confrontation.
Footage is unclear but Kent appears to shove Brown in the face, which would have been a red card offence if the officials had seen it.
Lennon believes that both incidents warranted a sending off and that Rangers should have ended the game with nine men.
As reported by BBC Sport, Lennon said: “[Brown has] been elbowed [by Morelos] and then pushed or punched in the face by another player and really Rangers should have been down to nine men.
“Ryan Kent, after we scored the second goal, has either slapped or punched him in the face and it’s just unacceptable at this level of football.”
Brown is, of course, the master of antagonising the opposition and was up for the challenge of the Old Firm.
There was a clear plan in place to invoke a reaction from Morelos and it was too easy to tease him into his fifth red card of the season.
Brown also provoked a reaction from Andy Halliday after the game, which earned the Rangers left-back a second yellow card.
While tempers and emotions will inevitably on display in an Old Firm clash, Morelos and Kent acted in an unacceptable manner and both deserved punishment.
