HAWTHORN defender Brian Lake has decided to challenge his rough conduct charge at the Tribunal after he was handed a $1500 fine for pushing Richmond forward Tyrone Vickery into the MCG fence on Friday night.

Lake, who could have accepted a $1000 penalty, will face the Tribunal on Tuesday night to clear what would be his first strike for a minor offence this season.

Meanwhile, Geelong veteran Steve Johnson's 250-game celebrations are on hold after he accepted a one-week suspension for striking Brisbane Lions midfielder Allen Christensen.

The Cats premiership star was due to reach the milestone against the Sydney Swans on Saturday night at Simonds Stadium, but was hit with the ban by the MRP after conclusive vision emerged on Monday.

The MRP said Johnson's action against his former Cats teammate was intentional conduct with low impact to the head, which drew a two-game sanction before his early plea.

All players aside from Lake accepted their penalties, with Fremantle defender Zac Dawson feeling the full force of the MRP for his errant elbow on Greater Western Sydney's Jeremy Cameron.

Dawson was hit with a two-match ban, with the MRP grading the incident as careless contact with high impact to Cameron's head, which came to a three-week ban.

It was reduced to two games with an early plea, which will see Dawson available for the Dockers' clash with North Melbourne in round 21.

Hawthorn defender James Frawley has been cleared from his match-day report for a rough tackle on Richmond forward Jack Riewoldt, with the MRP assessing the force of the tackle as not sufficient for an offence.

But North Melbourne defender Michael Firrito has not been as fortunate.

Firrito's late spoil on Carlton ruckman Matthew Kreuzer will be costly, with the senior North Melbourne defender to miss this week's meeting with Melbourne. His high hit has seen him given a one-week ban.

Young Carlton defender Dylan Buckley was fined $1000 for his sling tackle on Lindsay Thomas.

West Coast forward Mark LeCras was fined $1500 for engaging in rough conduct against Matt Shaw, while Jack Steven was charged with making "unreasonable or unnecessary" contact to Travis Boak.

The Saints midfielder accepted a $1000 sanction, as did his teammate Jack Newnes, who struck Robbie Gray in the club's loss to Port Adelaide.

Geelong veteran James Kelly was also fined for making contact with an umpire, while Melbourne skipper Nathan Jones, Giants midfielder Toby Greene and Cameron, Dawson and Freo star David Mundy were all handed fines for wrestling and melees.
