Collingwood giant Mason Cox will try his luck at the AFL Tribunal as he attempts to re-gain eligibility for this weekend's Grand Final rematch.

Cox was involved in an off-ball incident with Richmond defender Dylan Grimes, which had originally garnered a one-week ban from Match Review Officer Michael Christian.

Cox's bump was deemed to be intentional, while making low-level head impact.

Meanwhile, Richmond has decided not to challenge Grimes' one-game punishment for collecting Jamie Elliott with an elbow, meaning he will sit out Saturday's crucial clash with the Giants.
