The match review committee on Monday deemed the incident from Sunday's match at Olympic Park so serious that it referred it straight to the judiciary which is expected to hear the case on Wednesday evening.
Ross has been charged with striking and is facing a possible lengthy ban after hitting Cronk with his elbow well after the Storm halfback had put in a crossfield kick during Cronulla's 17-16 win.
His Melbourne counterpart Brett White is facing a three-match ban after being given a grade four striking charge for punching Ross in retaliation to the Cronk incident.
If White opts to contest the charge at the judiciary he risks a possible four-match suspension.
Meanwhile, the match review committee has cracked down on shoulder charges which misfired at the weekend.
North Queensland centre Ashley Graham faces a grade four careless high tackle charge but can escape with just a one match ban with an early guilty plea.
Graham's hit with what appeared to be an elbow left Wests Tigers captain Brett Hodgson concussed and highly doubtful to play this weekend against the Bulldogs.
Brisbane's Test fullback Karmichael Hunt is facing a one match ban after getting a grade three careless high tackle charge for his shoulder charge which left Sydney Roosters five eighth Braith Anasta with a broken nose on Friday night.
Manly frontrower Josh Perry is also looking at one match on the sidelines after receiving a grade one striking charge for allegedly headbutting Newcastle's Danny Wicks in a scrum.Like
