Television pictures on Monday showed Cabofriense defender Cleberson giving referee Ubiraci Damasio a peck on the cheek after having a foul awarded against him during a 3-1 defeat by Botafogo at the Maracana.

The two were initially involved in a friendly exchange but the referee's mood quickly changed as he pulled out a yellow card and could be seen to say: "You can't kiss me."

"I didn't know it was against the rules," said Cleberson afterwards.
