INNOCUOUS KNOCK THAT COULD’VE LED TO ‘DISTURBING’ INCIDENT … 45 MINUTES LATER

Melbourne defender Harrison Petty hinted at having blurred vision before he was ruled out with an unusual head injury.

Petty was unstable on his feet and needed assistance from the ground after taking an uncontested kick during the third quarter of the Demons’ win over Brisbane on Sunday.

The defender was immediately taken into the rooms and did not return to the field.

Melbourne coach Steven King said Petty could have suffered a serious delayed concussion from an earlier hit.

“We’re still having a bit of a look at that, potentially concussion or something,” King said, after a nail-biting win over the reigning premiers.

“We’ll do all the right tests but we’re not 100 per cent sure, but he was complaining of some blurred vision so we’ll do all the test tonight and tomorrow. Obviously, not great.

“I think it’s something he received that ball in the goalsquare and he probably thought ‘I should’ve stopped the game’.

“Whether it was something more sinister, whether it was delayed concussion, we’ll have a look at it.

“I think he mentioned something (about blurred vision) before, slightly before that kick, we’re obviously going to take it pretty seriously.”

Dual All-Australian Leigh Montagna watched vision of Petty back closely and pinpointed a marking contest in the second term — where Petty’s chin makes accidental contact with Lion Josh Dunkley — that might’ve led to his on-field instability some 45 minutes later.

“We found that incident and then I watched the rest of the play up until this moment — and I didn’t see one sign of him, up until that point, showing any signs of distress or light-headedness or anything like that,” Montagna told Fox Footy’s First Crack. “So, it was interesting to see how quickly it came on.

“The question is was it coincidence when it came on? It was the second time in the game where he kicked the ball directly to the opposition inside defensive 50 and had conceded a goal … it just then came on there.

“I watched even the 10 minutes before that, there was not one sign of him having any issues — and then, all of a sudden to come on like that, I thought was a bit bizarre.

“Even with a delayed concussion, to have your legs go under you like that out of nowhere, it was interesting.

“But again, we don’t know everything about delayed concussion. It was just the timing of it, I thought, was interesting.”

Dual premiership Kangaroo David King added: “I haven’t seen a delayed concussion hit like this … It is disturbing to watch.”
