The panel had the option of imposing a financial penalty on Lake, as it did recently for Greater Western Sydney's Jeremy Cameron and Richmond's Ty Vickery for headlocks.

Petrie was offered a reprimand for unnecessary contact to the face of Lake but declined, with his coach Brad Scott confirming on Monday night on Talking Footy the club would fight the charge at the tribunal on Tuesday night. In doing so the Kangaroos risk losing him for Saturday's home match against St Kilda in Hobart.

The panel, armed with a medical report on Lake it sought from Hawthorn, deemed Petrie's actions to have been negligent, low impact and high contact, triggering a 125-point penalty. A guilty plea would have cleared him to face the Saints but saddled him with 93.75 carry-over points, putting him on the brink of suspension for the next year.

On Sunday, Petrie said any contact to Lake had been unintended, but added he was bracing for punishment.

''I didn't mean to gouge or scratch him,'' he said on The Sunday Footy Show. "[But] I'm sure come [Monday] there'll be something go on and we might hear more about it.

"If that was my doing, putting the scratch on his face, I didn't mean to scratch him. I'm not a scratcher or a gouger or anything like that. I was just engaged in a bit of a wrestle and grabbed at something, as he had hold of me as well.''

Essendon's bid to follow up its morale-boosting win against Port Adelaide against arch-rival Collingwood this weekend has been hurt by a one-match suspension offered to midfielder Brendon Goddard for rough conduct against Kane Cornes.

West Coast forward Josh Kennedy has been offered a one-match suspension for rough conduct against Sydney's Zak Jones, a penalty that has been lessened from a base penalty of three matches due to his good record.

The incidents involving Goddard and Kennedy were deemed serious enough - Jones had to be substituted after the high bump he received from Kennedy in the second minute of the match - for at least a one-match ban.

Both players risk a two-match ban if they elect to fight the charge at the tribunal.

Gold Coast defender Rory Thompson and Brisbane Lions midfield general Tom Rockliff were each given a 125-point penalty for minor strikes. Thompson can escape with a reprimand, but Rockliff cannot because he is saddled with 69.75 carry-over points.

Rockliff would not risk missing a second match if he fought the case at the tribunal and lost.

GWS ruckman Shane Mumford has been offered a reprimand and 60 carry-over points for a negligent high strike on Adelaide's Josh Jenkins. He could go to the tribunal without risking missing a match if his challenge failed.

The Lions' Claye Beams has been offered a $1950 fine for a first offence for reckless umpire contact.

Essendon's Paul Chapman and Port Adelaide's Robbie Gray were cleared of strikes against each other as they scuffled.
