Sydney Roosters stars Sonny Bill Williams and Anthony Minichiello have entered early guilty pleas to their charges from the NRL season opener.

Williams was charged with a grade-two shoulder charge for his shot on George Burgess in the last minute of the first-round 28-8 loss to the Rabbitohs.

If he and the club had fought the charge and lost, Williams would have been ruled out for four weeks but the early guilty plea means he will be available for the round-five game against the Bulldogs.

Captain Minichiello was hit with a grade-one dangerous contact charge for raising his knee into the shoulder of Rabbitoh Lote Tuqiri as the winger tried to make a tackle.

Minichiello, the face of the league, will not serve any suspension and can line up for the Roosters' next game against the Eels.

Souths five-eighth Dylan Walker also took the early guilty plea for his charge of attempting to trip Williams and is free to play in the Rabbitohs' match against Manly at Gosford on Friday.

Broncos hooker Andrew McCullough was charged with a grade-two careless high tackle after he concussed Mitch Brown in the 42nd minute of Brisbane's season opener against the Bulldogs.

McCullough will be free to play Friday's derby against the Cowboys after taking an early guilty plea.

While Eels back-rower Peni Terepo was slapped with a grade-one charge for his high shot on Carlos Tuimavave which resulted in an eight-point try being awarded.
