Geelong coach Chris Scott has expressed his frustrations in seeing another high knee hinder one of his players in a ruck contest, calling on players across the competition to "stop doing it" after the AFL alerted all clubs it would be coming down hard on the action.

All-Australian Mark Blicavs was left in pain in the centre of the MCG on Monday after a raised knee from Hawthorn ruckman Lloyd Meek struck Blicavs' torso, with the Cats tall assisted off the field and in the hands of club medical staff in the opening term of Geelong's win.

The incident came two weeks after Blicavs' teammate Rhys Stanley was also injured by a similar action from Carlton's Tom De Koning, with the Blues big man charged by the AFL's Match Review Officer for kneeing before successfully challenging the charge at the Tribunal.

The outcome of De Koning's incident led the AFL to send a memo out to all clubs stating they're looking to stamp out the raised knee action and that Stanley should have been awarded a free kick.

In this week's encounter between Geelong and Hawthorn, Meek went unpunished for a similar action on Blicavs, prompting further frustration from Scott after the game.

Speaking to reporters following his side's 82-point win, Scott said the action "has to be taken out of the game".

"You can't do it," Scott said.

"The AFL sent out a memo that couldn't have been clearer, saying not only is that a free kick, that it is reportable. You cannot do it. It has to be taken out of the game.

"I've got a slightly different view on what constitutes justice in the AFL world, I've got no dog in the fight around the penalty to the opposition player. We want the free kick, I don't want to see the guy suspended. That doesn't help us anyway.

"Just stop doing it. That should be the message from the AFL; the disappointing thing is they sent out a memo two weeks ago saying they couldn't do it."

Blicavs was able to play out the match following a period on the interchange and under the assessment of medical staff.

Meek could be hit with a charge by the MRO for kneeing after De Koning was handed a $3000 sanction for his incident on Stanley before the Tribunal dismissed the charge.

The Hawthorn recruit won't be the only player from Easter Monday's clash facing a nervous wait, with both Cat Gary Rohan and Hawk Will Day potentially receiving charges for dangerous tackles.

Both clubs will head to South Australia for their Round 5 plans as Gather Round awaits, with the Hawks to face GWS and Geelong meeting West Coast at Norwood Oval and Adelaide Oval on Sunday respectively.
