Melbourne forward Danny Williams was charged with striking by the NRL match review committee today following his king-hit on Mark O'Neill on Saturday night.
Match review commissioner Greg McCallum referred the charge straight to the judiciary today without a grading, meaning Williams will have no option other than to face the panel on Wednesday night.
Wests Tigers back-rower O'Neill was also charged over the tackle which preceded Williams' moment of madness ? with a grade one careless high tackle offence.
Seconds after that incident, Williams knocked O'Neill out with a punch as the Tigers veteran was looking the other way.
Williams, who wrote a letter of apology to O'Neill yesterday, could be suspended for the remainder of the season.
O'Neill, who was cleared of any serious injury today, will not accrue enough penalty points to be banned.
Meanwhile, Penrith prop Ben Ross was charged with two offences today which could also end his season.
Ross was charged with a grade two striking offence and grade four dangerous throw.
The Queensland front-rower could face a three week ban on the former charge and eight weeks on the latter, with the combined suspension amounting to 12 weeks.
That would spell the end of the 24-year-old's year.
Ross would be banned for eight weeks if he entered early guilty pleas to the two offences, meaning he could return in the finals.
His Penrith teammate Joel Clinton was also charged with a dangerous throw for his part in the 35th minute tackle on Canberra's Jason Croker which led to Ross being charged.
Clinton was charged with a grade one offence and could miss a week.
The news wasn't good for Sydney Roosters forward Adrian Morley, who was charged by McCallum with a grade one careless high tackle following his 15th minute hit on St George Illawarra's Jason Ryles on Friday night.
Morley's poor record ? he has been suspended twice already this year ?would see him outed for three weeks if he contested the charge and lost and two weeks if he entered an early guilty plea.
And North Queensland forward Luke O'Donnell was charged with a grade one careless high tackle today.
He will not accrue enough penalty points to be suspended.Like
