Gray was stretchered from the field after a game-ending concussion that left him unconscious on the field for a number of minutes, dumped head-first in a tackle by Fremantle’s Ryan Nyhuis.
Hinkley, much like star-forward Jenkins, believes the incident commands at least some conversation on the reshaping of rules.
“(The tackle is) exactly what you’re not supposed to do,” he told afl.com.au.
“I don’t want to put anyone in trouble, but that’s why the injuries come about.
“Players don’t set out deliberately to cause injury like that. But when you tackle and you take that responsibility away from the player landing, you put yourself in trouble. So clearly there’ll be some trouble.”
Questioned on Monday morning in the wake of the incident, Jenkins said his opinion doesn’t sway a certain way, but a red-card system should be at least considered.
“My first thought would be no, but when you see a Harris Andrews or a Robbie Gray get the game ended — it affected Port big time yesterday because they’d already had an injury to a big player,” Jenkins told reporters.
“Irrespective of whether you consider the player injured one of the best or worst you’re still down.
“I remember looking at the stats last night and Port had only used about 50 rotations because they couldn’t get guys on and off the field.
“It has a big impact so it’s something worth talking about…I think it should be discussed but I don’t have an opinion either way,” he expressed.
It wasn’t long after Nyuhis’ tackle that players from Port protested angrily whilst Gray lay motionless on the ground, attended to by medical staff.
Fremantle coach Ross Lyon was quick to defend Nyhuis, saying his players “split-second decision” to tackle Gray was misconstrued and unintentional.
“No one intentionally goes out to hurt anyone and they’re split-second decisions,” Lyon told foxsports.com.au.
“Clearly it’s a split (second) decision and no one’s intentional.
“Our players have been driven into the turf unintentionally by the opposition. Sometimes it just happens.”
Both Lyon and Nyhuis are now at the mercy of a match review, with a suspension likely in the forward’s future.
