Fremantle's Michael Walters can accept a one-match ban for headbutting Melbourne's Jay Lockhart during their clash on Saturday at the MCG.

Port Adelaide duo Dougal Howard and Karl Amon can both accept one-match bans for separate incidents on Saturday night.

Howard has been cited for a gut punch to Geelong's Harry Taylor, while an off-the-ball hit has seen Amon land in hot water.

Western Bulldog Tim English ($2000), Fremantle's Luke Ryan ($1500) and Melbourne's Jayden Hunt ($1000) can all accept financial sanctions for separate incidents.
