Raiders fullback Jack Wighton.

Fullback Jack Wighton has been dropped from the Canberra Raiders side to play the Brisbane Broncos on Saturday night after pleading guilty to assault charges dating back to the 2018 pre-season.

Wighton pleaded guilty to two assault charges on Thursday in the ACT Magistrates Court and a charge of publicly urinating after an incident at a Canberra nightspot in February.

The Canberra Times reported seven other charges were withdrawn when he appeared before Magistrate Bernadette Boss.

Late Thursday the Raiders issued a statement saying Wighton would not take part in the round 16 Telstra Premiership game at Brisbane's Suncorp Stadium. The club's board will convene to decide any further action. 

"The Raiders will consult the NRL and are mindful that Jack was today referred to the Galambany Court next Wednesday 4th July," the club said.

"The Raiders Board will consider the matter further in the light of the Galambany Courts decision next week."

No other comment was made due to the matter now being before the courts.

It is likely Brad Abbey will come into the Raiders side at No.1.

Wighton returned to Canberra from a pre-game camp in Sanctuary Cove before this Saturday night's clash with the Broncos so he could attend court.

He answered charges stemming from an incident outside a Canberra nightclub on February 3, when he was accused of allegedly assaulting three people in the city's centre.

The 25-year-old initially pleaded not guilty when he firts fronted the ACT Magistrates Court in April.

He has played all but one game for the Raiders this season. Wighton is contracted to Canberra until the end of 2020, and has played 130 games for the club since debuting in 2012.
