Fremantle coach Mark Harvey has accused Carlton of using dirty ruck tactics as the fallout from Saturday's spiteful AFL practice match in Bunbury continues.

Harvey was upset that 211cm tap specialist Aaron Sandilands was held down in ruck duels by the opposing Blues' ruckman while a third man came over the top to win the knock.

After carefully reviewing footage of the game, Harvey called for the 'third man up' tactic to be outlawed and will meet with umpires' boss Jeff Gieschen in Melbourne this week to nut out the matter.

"What we are finding is that a lot of the opposition's ploys, or the (ploy of the) opposition ruckman, is to hold Aaron down and have a plan for the third man up after that," Harvey said on Monday.

"So I'll be discussing it with Jeff to get some clarity on it throughout the course of this week.

"I think it's something we need to discuss and clarify.

"What are ruckman for? They are obviously there to take the initial contest and let it decide itself after that.

I think we should take that (where only two ruckman can compete for the ball) right around the ground.

"I probably noticed it (holding the ruckman down so a third man can come over the top) more on the weekend.

"It's evolving. There's certainly a lot of it happening.

"There are a lot of rule changes that take place and a lot of things that we need to look at, this is possibly one of them."

Harvey's call came on the same day that Blues midfielder Nick Stevens was offered a one-match ban by the AFL match review panel for striking Fremantle youngster Nick Suban during the Dockers' 43-point win.

Simon Wiggins, who was reported for rough conduct after pinning Greg Broughton's arms in a tackle and slamming him into the ground, was cleared of any wrongdoing.

"Whether they were actually targeting us or not doesn't really faze me as a coach," Harvey said.

"I like to think that our younger players, it makes them grow up quicker, makes them understand what the big games are all about.

"I think what you saw is some of our senior players really look after our younger players."

Meanwhile, Harvey believes 22-year-old Broughton and 19-year-old Matt de Boer are capable of playing senior football this season after Fremantle elevated the rookies to their primary list.

"(We are) promoting two of our rookies because we don't have any veterans (on our list)," Harvey said.

"We look forward to those guys hopefully playing a role throughout the course of the year.

"We think they're physically prepared for AFL.

"They're both exciting young kids and they can actually put enough pressure on the senior listed players and you never know what happens throughout the year."
