Brisbane skipper Jonathan Brown may have to put the champagne on ice and keep the party poppers in the cupboard as a knee injury threatens to delay his 200th AFL match.

Lions coach Michael Voss said he would wait until Thursday, following consultation with club medicos, before deciding if Brown would be named for Sunday's clash with Adelaide at the Gabba.

He said Brown suffered a heavy knock to his knee during the Lions' win over West Coast last Saturday night at Subiaco Oval.

"He is in a little bit of doubt coming into the game," Voss told reporters.

"He has obviously just tweaked his knee a bit and we just need to make sure that's okay.

"It just got a little bit swollen after the flight so we have just got to monitor it and make an assessment a little bit later in the week on how he is travelling."

Brown's more pressing concern is contesting a tripping charge at the AFL tribunal.

The result will have no bearing on whether Brown will play against the Crows because even if he loses the appeal, the worst result is a reprimand.

However, Voss said the purpose of contesting the charge was to ensure Brown's recent good record remained intact and there were no tribunal activation points hanging over his head should there be any further indiscretions.

"I think Browny just likes to have his good behaviour (record)," Voss said.

"He is pretty proud of what he has been able to do the last six years, I think he just wants to maintain that.

Early in his career Brown's aggression was questioned after he had a horror run at the tribunal.

But for the past five seasons he has been able to stay out of trouble which Voss said could be attributed to a change in Brown's attitude and his leadership qualities.

"I've never seen a player more mauled in all my life when he plays," Voss said.

"It takes a fair bit to stir the big fella now and he shows enormous restraint.

"In actual fact I think that at times he should blow up more."

The injury-hit Lions may have some relief in sight with Amon Buchanan, Xavier Clarke (hamstring), James Polkinghorne (quad) and Justin Sherman (hamstring) all being considered for a return this round.
