Newcastle and Fiji forward Korbin Sims will miss his nation's Test match against PNG on Saturday night at Pirtek Stadium after accepting a one-match ban for a grade 2 careless high tackle. 

The charge comes from Sims' challenge on Roosters winger Joe Burgess in the Knights Round 9 loss at Allianz Stadium.

Cronulla forward Jayson Bukuya will also miss a match after pleading guilty to a grade 1 shoulder charge on Broncos halfback Ben Hunt. 

Bukuya will miss his side's Round 10 game against the Knights. 

Warriors halfback Shaun Johnson also pleaded guilty to a grade 1 tripping charge, but will not be suspended for any matches.
