Salford forward Lama Tasi faces a two-match ban after he was charged with striking with the shoulder in his side's Challenge Cup semi-final defeat by Wigan.
The Rugby Football League's match review panel viewed the tackle on Wigan prop Taulima Tautai as a grade B offence and Tasi must face a disciplinary hearing in Leeds on Tuesday.
The recommended maximum punishment is a two-game suspension, which would rule Tasi out of Friday's trip to Hull and the home game against Castleford seven days later.
Wigan's 27-14 victory which booked a Wembley date with Hull could come at a cost after hooker Sam Powell was charged with grade B dangerous contact on Tasi in a separate incident.
Powell has the option of submitting an early guilty plea and accepting a one-match ban that would see him miss Friday's Super 8s meeting with Leeds at Headingley.
Warriors team-mate Frank-Paul Nuuausala received a caution for raising a knee in the tackle.
There were no charges from Hull's 43-24 win over Leeds on Saturday.
