GREATER Western Sydney small forward Toby Bedford will miss the Giants' elimination final against St Kilda after failing to have his one-match rough conduct ban overturned or downgraded at the Tribunal.

Bedford was charged for his off-the-ball bump on Carlton defender Zac Fisher in the third quarter of the Giants' round 24 win at Marvel Stadium.

The contact was graded as careless, medium impact and high contact, drawing a one-match ban, after Fisher required a concussion assessment at three-quarter time, which he passed.

GWS argued the bump was not high or forceful and should not be considered medium impact.

Both of those arguments were rejected by the panel of Jeff Gleeson, Darren Gaspar and Scott Stevens, who agreed with AFL counsel Lisa Hannon's argument the potential to cause a head injury meant the bump should be considered medium impact.

Hannon also said the manner in which Bedford approached the ball was unreasonable in the circumstances as he could have elected to shepherd or block without bumping Fisher as strongly as he did.

Gleeson cited video and still photo evidence of Fisher's head appearing to come into contact with Bedford's body in a whiplash motion, and the forward holding his jaw after the incident.

Bedford did not speak during the hearing, with the Giants relying heavily on testimony from Fisher, who said the bump was not high.

"It was front shoulder against his shoulder," Fisher said.

"Through the shoulder, it was a good bump - but I definitely could've protected myself a little bit better."

Fisher said he had hadn't wanted to be assessed for concussion as he was "feeling a-OK to continue".

He had no marks, bruising or swelling left from the contact.

The Giants also turned to evidence from a biomechanist, while there was also a back-and-forth between Hannon and GWS counsel Ben Ihle regarding the definition of "forceful" contact.

Bedford has played 16 games in his first season at the Giants after he was traded from Melbourne, kicking 10 goals and averaging five tackles per game.
