Des Headland and Adam Selwood's heated clash in the western derby on Saturday night will have an explosive postscript on Tuesday night at the AFL tribunal.

AFL investigations officer Bill Kneebone has charged West Coast's Selwood with insulting language towards Fremantle's Headland in the third term of the match.

Fremantle took the unusual step of asking the AFL to investigate the matter.

"The incident has been referred directly to the Tribunal for its determination on the matter and the player is not able to enter an early plea," the league said in a statement.

Soon after Selwood's alleged comments, the pair clashed heatedly and the match review panel charged Headland with two striking offences.

He faces a total of six weeks' suspension, plus the panel has fined him $1200 for wrestling Selwood.

In asking the AFL to investigate, Fremantle had alleged Selwood insulted a member of Headland's family.

The Docker was furious for the rest of the game and lunged at Selwood again after the final siren.

It has also been alleged Headland told former West Coast player Drew Banfield, now a boundary rider for pay-TV network Foxtel, to inform Selwood he would "kill him" if he repeated the insult.

Headland is likely to take his two striking charges to the tribunal.

He faces a three-match ban per incident, owing to his poor tribunal record.

The Docker could reduce the suspensions to a total of five games and the fine to $900 with early pleas.

After a separate investigation, Kneebone also charged fiery Fremantle midfielder Josh Carr with striking West Coast's Daniel Chick.

Carr faces a three-match ban, but can accept a two-game suspension with an early plea.

The league also fined Michael Braun $5000 for his much-publicised foul language on live television after the game.

Braun urged his teammates to have a "f***ing good year" in his post-match speech.

He made the comment to the Subiaco Oval crowd while accepting the Ross Glendinning Medal for best afield in the match.

The remark was also broadcast on live television.

"The AFL had taken action as the player's swearing during the presentation of the Ross Glendinning Medal in front of a large match-day and television audience was totally inappropriate," the league said in a statement.

In other tribunal news, the panel handed St Kilda full-forward Fraser Gehrig a one-match ban for striking Western Bulldogs opponent Brian Harris.

Gehrig faces a one-match ban, even if he accepts an early plea.

Hawthorn defender Danny Jacobs received a $3200 fine for negligent contact with field umpire Dean Margetts, although an early plea would reduce it to $2400.
