Triple AFL premier Brisbane suffered badly at the Tribunal, losing Jamie Charman to suspension and failing to have Jonathan Brown's ban overturned.

The two marathon hearings altogether lasted more than three-and-a-half hours, but the injury-depleted Lions' efforts came to nothing ahead of their match on Saturday against Fremantle in Perth.

The tribunal found Charman guilty of striking Carlton's Adrian Deluca, significantly disregarding the evidence of the two players, and suspended him for two games.

Brown was found guilty of striking Blues onballer Darren Hulme and also received a two-match ban.

Brisbane called in several witnesses for Brown's appeal hearing - coach Leigh Matthews, field umpires Scott McLaren and Adam Davis, boundary umpire Danny O'Connell and a biomechanist.

Brisbane was arguing against Brown's verdict and penalty, but the appeals panel upheld them.

The only good news for the Lions was that the Queensland state league tribunal found rookie Anthony Corrie not guilty of his striking charge, meaning he will be available for the Perth trip.

Charman was booked after an AFL investigation into a second-quarter incident involving Deluca on Saturday night at the `Gabba.

AFL tribunal chairman Brian Collis described Charman's blow as "totally unnecessary" and "forceful".

"It was consistent with a punching action and given that it was a backwards and forwards movement, it is not consistent with a grabbing action," Collis said.
