Penrith's Viliame Kikau has been handed a one-match ban for a shoulder charge on St George Illawarra's Darren Nicholls.
Kikau was charged with a grade one shoulder charge and could now miss his side's clash against the Raiders next Sunday.
An unsuccessful trip to the NRL Judiciary will see the 24-year-old miss two matches.
The Panthers have until 12pm on Sunday to decide whether or not they will challenge the ban.
