The Warriors will be without front-rower Sam Lisone for the next fortnight after the NRL match review committee charged him for a raised forearm.
Lisone accepted the two-match ban after being cited for dangerous contact for an incident on Tariq Sims late in his side's win over the St George Illawarra Dragons in Wollongong on Saturday.
The 24-year-old hit the New South Wales Origin back-rower with a raised forearm in the 64th minute of the match.
He was hit hard by the committee because of his poor record, which includes three similar offences during the past two years.
As a result, he will miss Friday's game against the Newcastle Knights and the ensuing game against the Canterbury Bulldogs.
If he appealed to the judiciary, he risked being suspended for three weeks because of carryover points.
Bunty Afoa was also hit with a grade one dangerous contact charge on Dragons forward Leeson Ah Mau, but he will be free to play the Knights with an early guilty plea.
The Warriors will name their squad to face the Knights at 5pm on Tuesday.
