Petrie backed away from comments he made post-match that he was "nearly asleep there for a moment" when Lake appeared to apply a choker hold on him during the Kangaroos' win on Friday night.
He told The Sunday Footy Show he wasn't scared as Lake held him down with a hand around his throat for an extended period, saying, "I'm OK with it. It's a physical game, things happen in games".

Lake is expected to be referred direct to the Tribunal when the Match Review Panel announces its findings on Monday afternoon, with the defender likely to face a misconduct charge.
As he tried to free himself, Petrie appeared to claw at Lake's face before seemingly losing the ability to retaliate.
"I was just going to grab something because he had me … I didn't mean to gouge or scratch him," Petrie said.
"I'm sure that come tomorrow there'll be something go on and we might hear more about it."
Hawks; vice-captain Jordan Lewis condemned the undisciplined actions of Lake, who was comprehensively beaten by Petrie, conceding five goals in two-and-a-half quarters.
The 2013 Norm Smith medalist became increasingly frustrated in the third term, giving away a 50m penalty before the pair scuffled.
Lewis told SEN on Saturday the Hawks would not tolerate that kind of behaviour.
"I think he understands that what was done last night is probably not acceptable at our club," Lewis said.
"He's probably been known in the past to do stuff like that and have brain fades, but we haven't seen that at our club as yet.
"We saw it last night which is not what we expect from our players, and I think Clarko will have a word to him on Monday and it'll be resolved."
Kangaroos defender Lachie Hansen didn't see the incident on the night, but was pleased with how Petrie responded in his performance.
"He was all right [after the game]," Hansen told SEN on Saturday.
"He was up and about because he kicked his five.
"I saw the vision on the television this morning - it wasn't great but he had the last laugh kicking five."
