Richmond's Ellie McKenzie is free to face Port Adelaide on Tuesday night, after her one-match suspension for rough conduct was downgraded by the AFLW Tribunal on Monday morning.

The star midfielder's charge of rough conduct against Carlton's Dayna Finn from last Thursday night, was re-graded by the Tribunal as careless conduct, low impact and high contact.

As such, McKenzie had her suspension downgraded to a fine, and can line up for Richmond against the Power at Ikon Park in the first match of Week 5 of the AFLW season.
