What mattered more – the furniture or the fence – will help decide Jeremy McGovern’s fate at the AFL tribunal.

West Coast will front Tuesday’s hearing to argue against his one-game rough conduct ban.

McGovern was charged for an incident where he pushed Essendon’s Matt Guelfi, who then collided with a chair and the fence, on Thursday night at Optus Stadium.

“The chair defence will come into play here – I’m not sure if McGovern had to scan the boundary line for a plastic chair before he made an indiscretion on the field,” Eagles coach Adam Simpson told Channel Seven’s Talking Footy.

But match reviewer Michael Christian said it was Guelfi’s collision with the fence, not the chair, that earned McGovern his suspension.

“While he did hit the chair with his torso or midriff area, this charge was about the contact with the fence,” Christian said.

McGovern could have company at the tribunal, with Fremantle likely to challenge Michael Walters’ one-game ban for headbutting.

But the Dockers would appear to have plenty going against them if they decide to head to the tribunal, given there is minimal video footage of the incident.

Christian also said the evidence of reporting umpire Curtis Deboy was a significant factor in Walters being charged.

Meanwhile, Port Adelaide will weigh up whether to fight Karl Amon’s one-game rough conduct ban and a one-match striking suspension handed to Dougal Howard.

Amon was suspended for the bump that concussed Geelong forward Gary Rohan, while Howard is in strife for gut punching Cats veteran Harry Taylor.

“Particularly in the Amon one, we understand that the bump and what happens (from) the bump is really important to the match review, so we probably get that,” Power coach Ken Hinkley told AFL360.

But Hinkley is not so sure that Howard’s punch warranted the one-game sanction.

Fremantle and Port have until late Tuesday morning Melbourne time to decide whether to go to the tribunal.
