Warriors front-rower Sam Lisone is facing up to three weeks on the sidelines after being hit with a grade one dangerous contact charge following yesterday's 18-12 NRL win over St George Illawarra.
The 24-year-old is in hot water after he connected with a raised forearm on Dragons second-rower Tariq Sims during the second-half at WIN Stadium.
Lisone has already served a one match ban this season for raising his arm twice in the round three win over Canberra, and will need to contest the charge to have any hope of playing in Friday's home game against Newcastle at Mt Smart Stadium.
Lisone was also on the receiving end of a similar incident earlier in the match when a raised arm from Dragons second-rower Tyson Frizell hit him in the throat and left him requiring attention from the trainer.
However, unlike Lisone, the New South Wales State of Origin forward has escaped further scrutiny.
When asked about the Lisone incident involving Sims, coach Stephen Kearney was philosophical about whether he would have a case to answer.
"I'm sure there's a dozen or so incidents in a game," said Kearney.
"I do remember the incident, I don't recall the specifics or details. If he has something to answer for then he has something to answer for."
Fellow Warriors interchange forward Bunty Afoa has also been slapped with a grade one dangerous contact charge on Dragons forward Leeson Ah Mau but will be free to play the Knights with an early guilty plea.
