Brad Symes is waiting for a specialist’s opinion to find out the severity of his jaw injury.

Symes copped a high knock on Friday night and was subbed off at half-time. He is the only Crow from the game in doubt for Sunday’s Balfours Showdown at AAMI Stadium.

Matthew Jaensch (shoulder) will miss at least one more week and Ian Callinan (hamstring) will probably miss two more games.

Shaun McKernan, who did not play in the SANFL on the weekend because of a corked thigh, hopes to be available.

The players today cancelled a planned day off to start some training and review Friday night’s loss to St Kilda.

The main training session this week is on Thursday night (closed) and the team to play Port will have a light run on Saturday morning.
