The AFL match review panel is scouring television footage for an alleged biting incident involving West Coast midfielder Chris Masten.
Fremantle’s Nick Suban claimed Masten bit him on the arm while the two engaged in a wrestle in the third quarter of a spiteful western derby on Sunday.
Masten was not reported by match-day umpires but an AFL spokesman confirmed on Monday that the allegation had been noted by umpires and referred to the MRP.
If appropriate vision of the incident cannot be found the MRP will then launch an investigation.
While biting is not a specific offence under the MRP guidelines it can be classified as misconduct.
Fremantle went on to lose the match by 24 points, with the loss further compounded when defender Alex Silvagni was reported for striking Jamie Cripps in an off-the-ball incident.
Eagles coach Adam Simpson said after the match that Cripps had suffered a suspected broken jaw after Silvagni appeared to make high contact with his elbow.
