SYDNEY is again attempting to free Brownlow Medal hopeful Isaac Heeney from his suspension, taking the matter to the AFL Appeal Board on Thursday.

The Swans star was handed a one-match ban for a hit on Jimmy Webster during the club's loss to St Kilda on Sunday.

Sydney challenged the suspension but it was upheld at the Tribunal on Tuesday night.

The ladder-leading Swans have opted to go to the AFL Appeal Board, with the hearing to start at 5pm AEST.

Heeney has enjoyed a stunning season to date and is the equal leader on AFL.com.au's Brownlow Predictor, which correctly tipped Lachie Neale to win the award last year, after 17 rounds.

Under AFL guidelines, a Tribunal decision can be appealed on one of the following points:

    • Error of law
    • That the decision was so unreasonable that no Tribunal acting reasonably could have come to the decision having regard to the evidence before it
    • Classification of offence manifestly excessive or inadequate.
    • Sanction imposed manifestly excessive or inadequate
