The AFL's intent to prevent players sliding into contests is set to sideline a player for the second consecutive week. 

North Melbourne will challenge small forward Lindsay Thomas' offer of a three-match suspension for rough conduct over the incident in which Sydney's Gary Rohan had his leg broken yesterday.

While the incident received the most lenient gradings for intent and where contact was made, the impact made by Thomas was deemed to be severe.

Swans champion Adam Goodes had been due to play in that match too - and break the club's all-time games record - but was banned for one match for sliding into Port Adelaide's Jacob Surjan during a battle for possession in round three. Goodes fought the match review panel verdict at the tribunal but lost.

Geelong forward Steve Johnson may miss this weekend's match at Brisbane after being booked for two separate incidents against Richmond, for rough conduct against Chris Newman and tripping Daniel Jackson. Even if he accepts both charges the combined penalty will still be above the one-match threshold.

Cats ruckman Trent West can also accept a reprimand for rough conduct against Ty Vickery.

St Kilda key forward Justin Koschtizke has been offered a one-match suspension for striking his former teammate Zac Dawson, now of Fremantle.

GWS' Chad Cornes and Adelaide's Matthew Jaensch can accept reduced fines, $1800 and $900 respectively, for wrestling.

Cornes was spared a forceful front-on contact charge against Adelaide's Patrick Dangerfield, as was Essendon's Sam Lonergan for his tackle on Andrew Carrazzo that resulted in a broken shoulder blade for the Carlton midfielder.
