North Melbourne have elected to contest a kneeing charge laid against Jack Ziebell, with the AFL tribunal to hear three cases on Tuesday night.
AFL match review officer Michael Christian offered the Kangaroos captain a one-match ban after he kneed Reece Conca in the head in Sunday’s loss to Richmond.
He does not risk increasing the length of the ban if his challenge is unsuccessful.
Carlton brothers Charlie and Ed Curnow were both referred directly to the tribunal after they were deemed to have intentionally made contact with an umpire.
The Blues’ incidents came in their drought-busting win over Essendon on Saturday.
Their cases come after Geelong forward Tom Hawkins and Gold Coast co-captain Steven May were issued different punishments for touching officials in the past fortnight.
Hawkins admitted his crime in the Cats’ round seven clash with GWS and walked away with a one-week ban.
On Monday night, May was cleared to play in the Suns’ game in China when he was served a $1000 fine for his clash with official David Harris.
May was found not guilty of intentionally contacting the umpire, and guilty of the lesser charge of careless contact.
While Hawkins brushed away Dean Margetts in a gesture that could be seen as disrespectful, May was conversing with Harris and claimed not to feel the touch as he repeated the action that saw him give away a free kick.
“It was never my intention to make contact with umpire Harris,” May said.
“It’s unfortunate contact was made, it’s not an example I want to set for junior footballers across the country.”
Hawkins, who apologised for his action, said the barely-seen charge could make its way to the tribunal far more often if each interaction on a footy field was assessed.
“When you look at football, there’s a lot more player-and-umpire contact than brushes than you would probably think,” he said.
“Absolutely we respect the need and the role that the umpires play in the game.”
