Collingwood defender Darcy Moore avoids sanction for dropping knee into Fremantle Docker Josh Treacy

Collingwood defender Darcy Moore has been let off the hook for dropping his knees into Fremantle mach saver Josh Treacy on Sunday.

In the dying moments of Dockers’ heartstopping MCG triumph over the league leaders, Treacy stood tall on the last line of defence, collecting a rushed kick from former teammate Lachie Schultz on the chest.

However, Pies skipper Moore ensured the mark was earned, using his knees to plough into the back of the Fremantle forward, prompting the umpire to pay a 50-metre penalty that all but sealed the WA club’s famous victory.

The act sparked a minor melee that was also overlooked in the thrilling final moments.

Speaking post-game, Moore showed no concerns about being cited for the potentially dangerous action.

“Just fell into old mate’s back and, look, it was a physical game, clearly a high-pressure moment,” he told 7NEWS reporter Mitch Cleary.

“We expect that, we love that, that’s part of footy that we love, so I’d expect nothing less from the Dockers (then their response).”

He was right to be unconcerned, with the AFL not issuing a fine or suspension over the incident.

Former Melbourne great Garry Lyon was left scratching his head over the lack of consequences for the act and suggested it was “not a good look”.

“This is not a good look for the Collingwood captain, and I’m surprised he wasn’t given a fine, to be honest,” he said on AFL360.

“Dropping double knees, there was no reason to do that. So I don’t know. Why wasn’t that cited?

“It would have been a fine, I’m not suggesting a suspension.”

The lack of fine comes after one-day AFL footy boss Greg Swann bizarrely laid the blame for a baffling 50-metre penalty against Docker Karl Worner in the first half at the defender’s feet, even suggesting he should cop a spray from the coach.

Worner was penalised for umpire dissent after waving his arm towards the scoreboard after a marginal high-contact call on Schultz.

The penalty drew widespread criticism from fans and experts, with commentator Nick Riewoldt labelling the call as “ridiculous.”

However, Swann, who took over as head of football operations on Monday, defended the call.

“The interesting part about that stuff is if you’re going to give away 50m penalties by pointing at the scoreboard, and everybody knows you don’t do it, the coach would go nuts,” he said.

“My understanding is that there have been 13 of those paid this year; it’s not just that one, and some will argue that some have been missed as well.

“But everybody knows you’re not allowed to do that, so don’t do it.”
