Leeds forward Stevie Ward and Warrington hooker Daryl Clark have both been charged with punching offences arising from last Friday's Betfred Super League match at Headingley.
The pair were sin-binned an hour into the Rhinos' 40-0 victory and have been charged with grade B offences by the Rugby Football League's match-review panel.
Ward has the option of submitting an early-guilty plea but Clark, who served a one-match ban earlier in the season for striking, must face a disciplinary hearing in Leeds on Tuesday.
Clark's team-mate Joe Philbin will also appear before the disciplinary panel to answer a grade A charge of dangerous contact arising from the same game.
Salford prop James Hasson, who made his Super League debut in the Red Devils' 50-12 win over Catalans Dragons on Friday, and Catalans centre Krisnan Inu have been charged with grade A offences.
But the pair have the chance to avoid suspension by submitting early-guilty pleas, while Dragons scrum-half Richie Myler has been given a warning for tripping.
