Chris Heffernan will face the AFL Tribunal tomorrow evening after being reported on video evidence by umpire Shane McInerney for allegedly striking Mark Alvey of the Western Bulldogs. The incident occurred during the fourth quarter of the Round 14 match between Essendon and the Western Bulldogs at Colonial Stadium on Saturday 6 July. The Bombers could ill-afford to lose Heffernan with Dustin Fletcher already suspended and Joe Misiti and Mark Mercuri sidelined with injury.
