Western Bulldogs captain Katie Brennan will miss Saturday's AFLW decider against Brisbane at Ikon Park after the AFL Appeals Board upheld her two-game suspension.

Brennan was handed her second reprimand of the season and was subsequently banned for one match following this incident in the fourth quarter of her side's win over Melbourne last weekend.

The one-match ban was extended to two games after Brennan failed to overturn her suspension at the tribunal.
