It is believed the Roosters will argue there was no intent in Waerea-Hargreaves' actions, with suggestions first contact was with McQueen's chest.
But the risk is great for the Roosters given a guilty finding could have the potential for carry-over points to again cause major damage during the latter stages of the finals.
Whereas an early guilty plea would have left Waerea-Hargreaves with a one-game ban and eight carry-over points, a guilty verdict at the NRL judiciary would saddle him with 38 points.
That would mean even the most minor indiscretion would cost the Roosters' forward leader another one-game ban later in the finals - in a worse case scenario robbing him of a grand final appearance for the most innocuous of incidents.
Speaking before learning of Waerea-Hargreaves' charge, Rosters captain Anthony Minichiello was hoping for the best.
"I'm hoping he can be there,'' Minichiello said.
"He said it himself - there was no intent in it, so let's hope he can get off that.
Asked how big a blow it would be to lose him against a Manly pack known for its size and intimidation, Minichiello said:
"He's important, there's no doubt about that.
"He's one of our front row leaders there.
"He carts the ball up very strongly for us, he's been doing it all year.
"We want him in the side.''
