West Coast Eagles defender Jess Rentsch will miss Friday’s finals-shaping clash with Carlton after her one-match suspension for Rough Conduct was upheld at the AFLW Tribunal on Tuesday.

Rentsch was charged with Rough Conduct on Sydney's Montana Ham for an incident in the first quarter that was deemed Careless Contact, Medium Impact and High Contact.

The base sanction was a one-match suspension, with no option for an early plea, and the club made the decision to challenge the sanction at the Tribunal.

West Coast Eagles counsel David Grace KC, representing Rentsch, debated the impact should have been graded as low instead of medium, and that Rentsch had no alternative option of releasing Ham in the moment.

The Tribunal concluded that the tackle was correctly deemed Medium Impact, upholding the sanctioned one-match suspension.
