Fremantle star Michael Walters heads a list of three players facing one-game AFL suspensions.

Walters’ match-day report for headbutting Melbourne opponent Jay Lockhart was upheld, while Port Adelaide’s Dougal Howard was charged with striking, and teammate Karl Amon was suspended for rough conduct.

Also on Monday, West Coast confirmed they will take Jeremy McGovern’s one-game rough conduct suspension to Tuesday’s tribunal.
