Collingwood premiership player Mason Cox will have to explain himself to the AFL after shoving GWS ruck coach Shane Mumford in pre-match stunt.
In another chapter to the growing rivalry between the two clubs, Cox brazenly ran into the Giants' warm-up area during a ball-up drill at Homebush on Saturday night.
Cox pushed an unaware Mumford from behind, before jumping up and running away with the ball.
Mumford — one of the AFL's most imposing ruckmen during his career that ended in 2021 — and Giants players, such as Stephen Coniglio and Callan Ward, looked on in bemusement at Cox's antics.
The AFL has confirmed it will be issuing a 'please explain' to Collingwood over Cox's actions.
Giants forward Brent Daniels did not know about the incident until watching a replay after the Giants' 32-point win on Saturday night, but took full aim at the American.
"Mason likes to say things that get a bit of a headline," Daniels told the Nine Network on Sunday.
"He likes the limelight, but what he did before the game I thought was really bizarre. A bit of carry-on.
"I'd like to think we're really humble and hungry as a team.
"To see that wasn't a good look."
In a now-deleted post on his Instagram on Sunday, Cox said there had been "lots of false commentary" surrounding the incident.
"Will explain what actually happened on this weeks (sic) podcast," Cox wrote.
Cox failed to register a disposal in the first half of the Magpies' loss and finished with just five possessions for the match.
