West Coast midfielder Chris Masten and Fremantle defender Alex Silvagni must front the AFL tribunal after the spiteful western derby.

Masten was booked for biting Nick Suban after an AFL investigation, while Silvagni was booked during the match for striking Jamie Cripps well off the ball.

The match review panel referred the pair to the tribunal, with no option of an early plea.

Suban claimed Masten bit him on the arm while the two engaged in a wrestle in the third quarter.

A distressed Suban could be clearly heard via umpire microphones complaining to field umpire Jeff Dalgleish about Masten.

“He bit me, he f***ing bit me,” says Suban as he shows his arm to Dalgleish.

Masten was not reported by match-day umpires, but an AFL spokesman confirmed that the allegation had been noted by umpires and referred to the MRP.

The panel spoke to Masten and Suban before laying the charge.

Cripps has a suspected jaw fracture after Silvagni collected him, apparently with an elbow.

Collingwood defender Nathan Brown was also offered a one-game ban for rough conduct against Sydney onballer Luke Parker.

And North Melbourne midfielder Jack Ziebell can accept a one-match suspension for striking St Kilda’s Jack Newnes.

Port Adelaide defender Jackson Trengove faces a $1000 fine for rough conduct against GWS opponent Rory Lobb.

Trengove’s teammate Justin Westhoff has the same charge and penalty for an incident involving Giants star forward Jeremy Cameron.

Brisbane’s Luke McGuane was likewise offered a $1000 penalty for rough conduct against Carlton utility Kade Simpson.

Richmond star Brett Deledio can accept a $1000 fine for striking Gold Coast’s Aaron Hall.
