Collingwood captain Scott Pendlebury may have identified a possible loophole in the AFL's new rules - though he thinks Richmond got to it first.
Newly introduced starting positions mean teams need to start with six players in both of the 50m arcs and the centre square after goals and at the start of every quarter.
It's understood officials had told clubs they will give one warning if a player is out of position, paying a free kick for a second infraction.

Pendlebury, speaking on his Jock & Journo podcast, discussed a moment in the Magpies' win over Richmond last Thursday that the Tigers appeared to exploit the rule.
The 31-year-old claimed Richmond started with seven players in defence during a centre bounce late in the third quarter, prompting protests from their opponents.
"Our backs were going off their heads and our forwards were screaming ‘they have got an extra, they can’t have an extra'," Pendlebury said.
"You get one warning, which I think is going to create chaos, because if you get one warning you may as well burn one warning a game.
"It gives you a little bit more time to reset.
"I wonder now whether (clubs will exploit it), because clubs are all over this sort of stuff."
The Pies skipper even admitted that he floated the idea to his coach Nathan Buckley after the match considering Richmond successfully used the strategy.
"After the game I said to Bucks 'why don’t we use this as a tactic?'" Pendlebury said.
"If we need to get a rotation or whatever, just send someone back, cop a warning, then move them back to wherever you want or get the preferred positions you want and just go from there.
"You would do it."
The Herald Sun reports that the league had confirmed they missed the infraction during Thursday night's game, with the issue expected to be discussed among officials during the week.
Fortunately for Collingwood, they were still able to run out comfortable 44-point winners.
Pendlebury's side face another MCG blockbuster clash in round three - a Saturday night grand final rematch against West Coast.
