NSW winger Jarryd Hayne will blame poor hearing and his Parramatta teammates when he fronts the NRL judiciary on Wednesday night in a desperate bid to play in Origin II.

Hayne will seek a downgrade on his grade two dangerous throw charge on what should be an eventful night at NRL headquarters with North Queensland lock Luke O'Donnell to plead not guilty to two striking charges.

While O'Donnell is risking a seven match stint on the sidelines, Hayne could be rubbed out of the second Origin clash as well as three NRL matches should he not get his downgrade.

"It's going to be devastating (if I lose) because I'm going to miss a fair bit of time and it's pretty much my Origin series over," Hayne said.

"There's a lot that I'm risking to go in there, but I need to fight the charge to get off."

Hayne will argue he didn't hear referee Jason Robinson's whistle as he joined in as the fourth player into the tackle on Broncos lock Tonie Carroll.

Robinson called time off at which point the three other defenders released Carroll, Hayne continuing to lift the Broncos veteran before dumping him on his back.

"When I went in there I didn't hear the whistle and the blokes up top released Tonie when I had his legs," Hayne said.

"Hopefully they (the judiciary) can see it from that point of view."

The judiciary panel normally takes a dim view once a defender lifts a player by placing his hands between the attacker's legs, but the Blues hierarchy remain confident Hayne will be let off.

During the team's photo shoot Hayne remained in every shot while 18th man Joel Monaghan swapped places with Mark Gasnier, who remains in doubt with a hamstring injury.

Nonetheless Monaghan is expected to come in on the wing should Hayne be ruled out, though coach Craig Bellamy wasn't giving too much away.

"We'll have a look at that wing spot when the decision on Jarryd comes," Bellamy said.

"Obviously we've got a couple of options in mind ... we'll make a decision based on what decision Jarryd gets."

O'Donnell will fight to clear his name after being charged with two counts of attacking players with his elbow as he ran the ball against Penrith on Saturday night.

Each charge carries a three-week ban.

The second incident led to O'Donnell's sending off and verballing of the touch judge, the Cowboys lock pleading guilty to a contrary conduct charge for approaching a match official in an aggressive manner for which he received a one match ban.

"We believe there's a good enough case to prove to the panel that Luke is not guilty of both those charges," Cowboys chief executive Peter Parr said.

"(Luke's) made his feelings quite clear ... it's always been the policy of the club to back the player as much as we can in these circumstances."

Asked if O'Donnell would need to change his running style in the future, Parr said:

"Here's a guy that's played well over 100 NRL games, he's played 11 Tests for his country, he's played State of Origin football for his state and nobody's had a problem with the way he carries the football until Saturday night.

"So I'd be surprised if there was any great need for him to address anything."

The other three players charged all took the early guilty plea, including Brisbane centre Justin Hodges who will miss the remainder of the Origin series as a result of a grade three dangerous throw.

Hodges will return in round 20 against Cronulla while Manly's Adam Cuthbertson and Parramatta's Brendan Oake will both miss just the one game.
