Lycett was sent straight to the AFL tribunal on a rough conduct charge for the tackle.

The Power ruckman didn’t contest the grading of his sling tackle as careless, with severe impact and high contact.

The AFL’s advocate Jeff Gleeson called for a four-match ban at Tuesday night’s hearing, calling attention to Lycett “turning the body to increase the force” of his tackle”.

“What Lycett achieves in this tackle is that he wraps McHenry up, he then squares himself, he pivots, he rotates and he slams McHenry’s head into the ground,” Gleeson told the hearing.

“I’m not saying he intended to slam his head into the ground, the only question when it comes to severity of impact is what was the effect.

“And there is no other way to put it but that this dangerous tackle had the effect of not knocking the head into the ground … but slamming it into the ground.

“The impact is extremely forceful and the injury was considerable … the player is immediately limp. The potential was for even worse injury.

“In Lycett’s favour, he hasn’t come along here tonight and tried to minimise before you the nature and severity of his offence.

“It’s to his credit that he has accepted every single component of the charge … (but) a guilty plea does not get you a reduction of matches.’

McHenry has been sidelined for at the least the mandatory 12-day concussion period.

Port this morning said it had considered and accepted Lycett’s penalty.

“Scott plead guilty to all elements of the AFL’s charge and on that basis, we accept the tribunal’s sanction,” Port’s football general manager Chris Davies said.

“Unfortunately, mistakes can be made in the heat of the moment. Scott has privately expressed his remorse to Ned McHenry and has also done so publicly. As a club, we wish Ned well for his recovery.”

The ban means Lycett will miss Saturday night’s game against the Western Bulldogs along with games against Collingwood, Fremantle and Geelong.
