Carlton aren't giving up their fight to free captain Patrick Cripps from his two-game suspension just yet, set to take his ban to the AFL's appeals board on Thursday night.
The club announced via Twitter it would appeal the penalty confirmed on Tuesday night by the AFL tribunal.
Cripps is currently set to miss his side's vital final two regular-season games, having failed to overturn a rough conduct charge at the tribunal.
The Blues can punch their tickets to finals with just one more win, but will need to knock off either of top-ranked sides Melbourne or Collingwood to do that.
Cripps is facing the two-game ban for bumping Brisbane's Callum Ah Chee, his bump leaving the Lion concussed.
His hit was graded as careless, high impact and high contact, and AFL tribunal chairman Jeff Gleeson said upholding the ban had not been a challenging decision.
"(Cripps) entered the contest at speed, he saw a player at least in his peripheral vision and leapt into the contest," he said at the tribunal.
"Cripps could, and should, have contested the ball differently and in a way that did not present such a high and serious risk to his fellow player."
While the exact grounds for Carlton's appeal aren't yet clear, coach Michael Voss labelled the hit "a good contest" after his side's loss to Brisbane.
"The umpire probably told the story, didn't he? He didn't pay a free kick, did he?" he said.
"From what I've seen the arms were outstretched and it was a pretty even contest.
"If we are asking players to make micro-second decisions, I don't know whether the game enables that. I really don't."
