Salford half-back Rangi Chase looks like missing the Ladbrokes Challenge Cup fifth round clash with Leigh Centurions.
He faces the threat of a four to eight-match ban after he was charged with making a Grade E dangerous throw on Good Friday.
Leigh meet Salford at the Sports Village on Saturday, April 18.
The Red Devils went on to beat Huddersfield 18-12 to continue their recent good form, but they could now be without their mercurial stand-off for a lengthy period.
The Rugby Football League’s match-review panel viewed Chase’s tackle on Brett Ferres in the 15th minute of the match at the John Smith’s Stadium as dangerous and he has been asked to appear before an independent disciplinary tribunal on Wednesday evening.
Chase will be joined at Red Hall by Salford team-mate Weller Hauraki, Widnes’ Danny Tickle and Hull KR prop Mitch Allgood, who face Grade C, B and A charges respectively.
