Fremantle gun and Port Adelaide duo suspended by MRO

Michael Walters, Dougal Howard and Karl Amon have all been suspended.

The Match Review Officer has offered the trio one-game bans for separate incidents across the weekend.

Fremantle gun Walters was charged with headbutting.

Port Adelaide duo Howard (striking) and Amon (rough conduct) also came under scrutiny.

Jeremy McGovern, meanwhile, will challenge his one-game ban for rough conduct.
