It happened during the final minute of the first quarter when Blakey took a mark and fell to the ground with Smith in pursuit.

Blakey was on the ground and Smith was standing over him as the star Swan reaches out and appears to make contact with Smith.

Smith’s foot then makes contact with Blakey, who reacts by pushing him away.

The Lion then loses his footing and falls over. But as he is on the ground, he appears to reach out and make contact with Blakey’s backside.

The reverse angle of the incident, as revealed by 7NEWS in the player at the top of the page, was not seen as part of the match broadcast on the day.

7NEWS chief AFL reporter Mitch Cleary said the Swans, as well as Blakey, had no issue with the incident and did not issue a complaint.

“Both players and clubs were spoken to today and no further action will be required,” he said.

“The Swans stressing that neither the club or Blakey have any issue with the incident.”

The AFL released a statement late on Monday confirming they will be taking no further action.

“Following enquiries by the AFL Integrity Unit into an incident during the Brisbane Lions and Sydney Swans match on Saturday, it has been determined that no further action is required,” the AFL said in a statement.

The Agenda Setters’ Kane Cornes was aghast that the AFL sought no further action.

“I cannot believe that the AFL would look at that and say there’s no case to answer,” he said on Monday night.

“That’s one of the more unusual things I’ve ever seen on a football field.

“It didn’t look like (an accident).”
