The AFL Match Review Panel had booked Petrie for making unnecessary and unreasonable contact to Hawthorn defender Lake's face during the third term on Friday night at Etihad Stadium.

Petrie had been offered the chance to accept a penalty of 93.75 carryover points with an early guilty plea. But instead he chose to plead guilty but asked that the jury find that he acted in self-defence and the carryover points penalty should be thrown out.
Petrie had risked a one-game ban but he successfully argued he was in a potentially dangerous position with Lake lying on top of him and he simply pushed upwards to get his opponent off him.
"I think my hand was on his face for about two seconds. As soon as I realised I'd made contact with his face, I pulled my hand away," Petrie said.
"If I let him lie on my face like that, it's a position you don't want to be in for too long."
Lake threw Petrie to the ground and grabbed his throat as they wrestled.
Petrie then grabbed at the Hawthorn defender's face as he struggled to break free.
The jury deliberated for just three minutes before finding a reprimand with no carryover points was an appropriate penalty.
North coach Brad Scott had said he was flabbergasted that Petrie was charged.
"I'd ask any reasonable person to suggest what Drew should have done in that situation," Scott told the Seven Network's Talking Footy on Monday night.
