Brisbane captain Tom Rockliff will challenge his sanction for striking at the AFL Tribunal tonight.
Rockliff was fined $1,500 for striking West Coast's Matt Priddis during the Lions' loss to the Eagles on Saturday.
The 26-year-old could have accepted a $1,000 fine with an early guilty plea, but risks being fined the full $1,500 if his appeal is unsuccessful.
All other Round 13 charges were accepted.
