Contact between the Brisbane Lions’ Rhys Mathieson and Port Adelaide’s Chad Wingard from the third quarter of Saturday’s match was assessed. Port Adelaide’s Jared Polec kicks to Wingard, who marks the ball. Mathieson arrives at the contest as the mark is being taken and makes strong body contact to the back of his opponent.
