Panthers prop Sam McKendry charges forward.

Penrith's Sam McKendry will miss two matches after pleading guilty to a shoulder charge, while Roosters prop Dylan Napa will challenge his careless high tackle charge at the NRL judiciary on Wednesday.

McKendry will miss the Panthers' upcoming matches against Manly and South Sydney over the hit on Melbourne's Cameron Munster late in the Panthers' loss to the Storm on Saturday night.

Raiders duo Shannon Boyd and Jack Wighton are also suspended this week after pleading guilty to a shoulder charge and making contact with an official respectively.

Bulldogs hooker Michael Lichaa has entered a guilty plea to a dangerous throw charge on Cronulla's Chris Heighington but won't miss any matches.
