Fremantle star Michael Walters is on report for headbutting and could be looked at for striking in an unwanted footnote on Sunday’s epic three-point win over Adelaide.

Walters and Crows defender Kelly tangled late in a tense last quarter with the ball on the half-forward line and the Dockers hanging onto a narrow lead.

Walters threw a round-arm punch to the abdomen of Kelly, which sent the defender to the ground and saw a free kick awarded to the Crows.

And if that wasn’t bad enough, the Freo star followed that up by making contact with the head of Tom Doedee, who had come in to remonstrate.

The second contact saw umpire Brendan Hosking award a 50m penalty and put Walters on report for headbutting.

Walters was dragged from the bench, unhappily cooling his jets on the bench for the final few minutes of the game.
