Manly's Anthony Watmough is facing a two match ban for a chicken wing tackle after being charged by the NRL match review committee on Monday.
Watmough was handed a grade two unnecessary arm pressure/dangerous contact charge for his 39th minute tackle on Warriors fullback Kevin Locke on Saturday night.
The 28-year-old will have until midday on Tuesday to fight the charge at the judiciary on Wednesday night - where he would face a two-match ban if he fights and loses.
"We'll be reviewing the footage and we'll make a decision (on Tuesday)," a club spokesperson said.
An early guilty plea would rule him out for just this weekend's important clash with North Queensland.
Any suspension to Watmough could leave Manly sorely depleted in the forwards, with co-captain Jason King only a slight chance of being fit to face the Cowboys in Townsville.
King suffered severe bruising to his chest during the Sea Eagles dramatic comeback victory over the Warriors in Perth.
And while he has been cleared of any serious damage, he will be monitored this week before the club makes a decision on his involvement.
The Sea Eagles are currently sixth on the ladder on 26 points but face a tough run home, playing three of the competition's top four sides in the final five rounds, with away fixtures against South Sydney and the Cowboys and a home clash with Brisbane in round 25.
Melbourne halfback Cooper Cronk escaped punishment for his tackle that left St George Illawarra's Ben Creagh in some distress on Friday night.
