ADELAIDE star Bryce Gibbs will challenge his rough conduct charge at the AFL Tribunal, but captain Taylor Walker has accepted a one-game suspension for his bump on Zach Tuohy.

Gibbs was fined $3000 for flooring Geelong skipper Joel Selwood in an off-the-ball incident on Thursday night, with the contact deemed careless with low impact to the head.

The punishment drew the ire of Gibbs' teammate Hugh Greenwood, who tweeted "Surly [sic] a piss take?" upon hearing of the financial penalty.

However, Walker won't go to the Tribunal on Tuesday evening, having accepted a one-match ban for rough conduct following an incident involving Tuohy.

Walker caught Tuohy high and late, with the Cats defender forced to leave the ground for a short period. He later passed a concussion test and played out the game.

Carlton utility Jed Lamb has also accepted his one-match ban for making contact to the eyes of St Kilda forward Jade Gresham on Friday night.
