"Healy was cited on the grounds of an "act contrary to good sportsmanship".
New Zealander Hampton, an independent judicial officer appointed by the Australian Rugby Union, concluded it was possible that during the incident, Sheehan's arm "may have come in contact with Healy's mouth and due to the pressure of the tackle it is likely that unavoidable contact between Healy's mouth and Sheehan's arm occurred".
"There is no conclusive video evidence of the incident and post-match it was not possible to distinguish any discernible bite marks outside of the 'regular' marks usually found following a rugby match," Mr Hampton said in his findings.
"I cannot prove on the balance of probabilities that there was a deliberate bite here and the citing complaint is not upheld."
Sheehan, speaking on Australian television as the players came off at half-time, said: "I don't know if it was an accident or on purpose but there it is. We move on."
you should have moved on at the time Sheehan and said nothing - it's made you look like a dick. as does the citing commissioner.
