Gold Coast has decided not to challenge Steven May's three-match suspension at the Appeals Board.

The SUNS had until midday on Wednesday to indicate if they would appeal the Tribunal's penalty for May's high bump on Brisbane Lions captain Tom Rockliff.

They would have needed to make a case under the four grounds for appeal:

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

Melbourne's Jack Viney last season became just the second player in 15 cases to have his charge overturned after he was cleared of responsibility for breaking Adelaide forward Tom Lynch's jaw in a high bump.

Fremantle star Nat Fyfe later failed at the Appeals Board after the Dockers fought his charge of striking Hawthorn midfielder Jordan Lewis.

May could have accepted a two-week penalty from the Match Review Panel but chose to challenge and will now miss matches against Adelaide, West Coast and Collingwood.

The Tribunal decided he had a realistic alternative way to contest the ball instead of bumping his opponent and making high contact.
