London Broncos hooker James Cunningham has been referred to the tribunal after an allegation of racist language was made against him.
The complaint was made during the Broncos win at Hull KR last week, as words he used towards Mose Masoe were brought to the attention of referee James Child, who put the incident on report.
He has now been charged with a Grade F offence of using unacceptable language. If found guilty, he faces a ban of up to eight matches.
Also heading to the tribunal is Matthew Wright of Newcastle Thunder, who has been charged with a Grade D high tackle on Tom Halliday during their defeat against Doncaster.
If found guilty, he faces a ban of up to five matches.
Meanwhile, Matty Smith of Warrington Wolves and Oliver Partington of Wigan Warriors will both miss their sides opening playoff matches after being charged with dangerous contact and striking with the arm respectively.
Castleford Tigers front rower Jesse Sene-Lefao will miss the Tigers’ next two games after he was sent off for striking with his knees.
Also, Leeds Rhinos pair Matt Parcell and Luke Briscoe will miss the start of the season after being banned for three and one games respectively. Parcell was charged with dangerous contact and Briscoe has been charged with drops with knees.
Finally, Danny Tickle will miss Workington Town’s game against Newcastle after being given a one match penalty notice for dangerous contact.
