Nat Fyfe's Brownlow Medal eligibility is intact after his trip at the weekend was deemed only worthy of a fine by the match review panel, while Steve Johnson escaped penalty altogether for contact to the groin of an opponent.

The elite Fremantle midfielder's trip of Western Bulldogs' Koby Stevens was rated as intentional, low impact and body contact. It triggered a base penalty of a $1500 fine, which can be cut to $1000 with a guilty plea.

Even though the Dockers may grumble about the incident being rated as intentional - coach Ross Lyon argued the part of Etihad Stadium it occurred on was conspicuously slippery - the penalty was not any higher than it would have been had it been instead judged careless. Fyfe was only facing suspension if the impact to Stevens was rated medium or above.

Under the new tribunal rules a player is only ineligible for the Brownlow if they miss a match due to suspension. Furthermore, increased penalties for a bad record, such as Fyfe's for missing four matches in the past two years, only apply to suspensions, rather than fines.

Johnson's swat at Sydney's Jarrad McVeigh as they battled to gain possession did not result in a charge, with the panel deeming it was a legitimate attempt to get in a good position to get the ball ahead of his opponent.

Had Johnson been charged and his strike deemed intentional conduct he would have received a three-match ban that could have been cut to two with a guilty plea. Had it been deemed careless it would have triggered a fine of $2500 that could be cut to $1500.

Crucially, the latter would have resulted in Johnson missing at a match if he was found guilty of a minor offence later this season, as players can only be fined twice for such offences before suspensions apply.

No players are facing suspension after round seven, with the other two players charged - North Melbourne's Jarrad Waite and GWS' Devon Smith - able to accept $1000 fines.

Waite has been charged with rough conduct for barging into the back of Essendon's Zach Merrett in a late spoiling attempt. Smith was also charged with rough conduct, against Carlton's Bryce Gibbs. Both were deemed careless and low impact, with high contact for Waite and body contact for Smith.

In addition to Johnson, Western Bulldogs' Lin Jong also avoided charge following scrutiny from the panel, for his clash with Fremantle's Michael Walters. The panel said Walters should have received a free-kick but Jong's action was nevertheless a legitimate attempt to win possession.
