North Melbourne coach Alastair Clarkson will have to explain himself to the AFL over his "inappropriate" outburst towards St Kilda's Jimmy Webster and Dougal Howard, with a sanction potentially on the cards.
Clarkson was incensed after Webster's high, late bump on Jy Simpkin in Sunday's practice match left the Kangaroos co-captain in concussion protocols and the Saints defender with an imminent tribunal hearing.
