Argentine loose-forward Leonardo Senatore was banned for nine weeks for biting in 2013.
In the weekend Super Rugby action, Senatore bit a rival Sharks forward and was banned for 10 weeks.
None of the discussion, argument or details about the incident are included in a statement from Sanzar after the video hearing, only a few paragraphs about the incident and the decision.
The three-man judicial committee, chaired by Adam Casselden, decided Senatore's latest offence deserved the lowest ban of 12 weeks.
They noted his previous conviction and added two weeks for that before reducing the penalty by a month for his good behaviour.
