Rangers manager Steve Gerrard admits he cannot defend Alfredo Morelos any more after the Gers striker was sent off again in the 2-1 defeat at Parkhead.
Morelos was dismissed by referee Bobby Madden for throwing an elbow at Hoops skipper Scott Brown - his fifth red card of the season, albeit the first was rescinded.
Gerrard, who confirmed defender Andy Halliday had been shown a second yellow card in an unsavoury post-match melee between the players on the pitch, gave a simple reply when asked if he could still defend Morelos.
"No. Not no more," he said.
"I have gone above and beyond for Alfredo. I have continued to protect him, support him and love him as a player and the person he is but I have to draw the line under it now and he will be punished internally.
"I will recommend to the board that he is fined a week's wages and will also recommend that the fine should go to the supporters who came today because they are the ones who will suffer from his indiscipline, also his team-mates as well.
"The money is of no use to his team-mates, it is more use to the fans."
Gerrard promised a tougher approach to discipline within his squad when asked if Morelos could change his ways.
He said: "That's a question you will have to ask the player. I can honestly say I have done everything I can. His team-mates have done everything they can, my staff and support staff have done everything they can."
But Gerrard had sympathy for Halliday, who clashed with Brown after the Celtic player celebrated in front of the 800 Rangers fans at the final whistle.
He said: "I feel for Andy. Celtic are well within their rights to celebrate.
''But I can't understand why a guy decides to celebrate 10 yards away from two per cent Rangers fans rather than 98 per cent of his own support.''
