Brisbane Lions fans were left seething last night after Geelong capitalised on a clear throw to kick a goal.

Gary Ablett kicked a goal in the third term from a Patrick Dangerfield throw.

Unfortunately for Brisbane, the umpire did not have a clear view of the incident and award a free-kick.

Channel Seven commentator Brian Taylor raised the incident on-air but fellow commentator Wayne Carey had sympathy for the umpires.

โ€œHow is the umpire meant to pick up on that though.? He canโ€™t see it,โ€ Carey said on the telecast.

The incident did little to change the result as the Cats stormed into their first Grand Final since 2013 courtesy of a 40-point win.

Ablett wound back the clock to kick two goals in the stunning win.
