COLLINGWOOD defender Marley Williams has been reported for striking, while Western Bulldogs star Adam Cooney has suffered a hamstring injury following an eventful first quarter at Etihad Stadium.
Williams was booked after an incident involving Nathan Hrovat just seconds before the quarter-time siren, which sparked a mini-melee.
A suspension would hurt the Pies, who face reigning premier Hawthorn next Saturday afternoon at the MCG.
Earlier, Cooney was substituted out of the game and replaced by fellow veteran Daniel Giansiracusa.
