GOLD Coast coach Stuart Dew believes Nick Holman executed a perfect chase-down tackle in the incident that saw the utility slapped with a two-match ban for rough conduct.

The Suns will challenge the suspension at the Tribunal on Tuesday night.

Holman won a holding-the-ball free kick for the tackle on Geelong's Mitch Duncan in Saturday's match at GMHBA Stadium.

But the Cats midfielder hit his head on the turf and was substituted out of the match under concussion protocols.

Match Review Officer Michael Christian considered the incident a dangerous tackle, deeming it careless conduct, high impact and high contact - which draws a two-match ban.

"If you wanted to look up in the dictionary a chase-down tackle, we think he (Holman) executed that pretty well," Dew told Fox Footy on Monday night.

"It's a football action, but we'll go through that (Tribunal) process tomorrow night.

"We're confident, given that whether you look at it in fast or slow motion, he did everything possible in duty of care and to execute a tackle within the laws of the game."

Dew said he wasn't surprised the incident was looked at by Christian, given the competition's strong focus on concussion and protecting players' heads.

But he admitted Holman was "disappointed and a little bit surprised" upon learning he had a case to answer.

"Once we informed him of that, we said really clearly we'd like to challenge it and I think he felt a little bit more comfortable on the back of that," Dew said.

"Nick's a player that loves playing footy for our footy club and he's the last bloke that's going out to try and injure people.

"For a minute there he (thought) he might miss two weeks while he's fit and healthy."

Gold Coast (3-7) takes on Hawthorn (2-8) in Darwin on Saturday night.

The Suns have a bye in round 12, meaning Holman will not be available until the clash with Port Adelaide on June 19 if his ban is upheld.
