Leeds' Anthony Mullally, St Helens' Kyle Amor and Hull's Bureta Faraimo are all set to miss the Dacia Magic Weekend through suspension.
Front row forward Mullally has been give a two-match penalty notice for four incidents of illegal use of his knees during the Rhinos' 23-20 win over his old club Widnes in their Ladbrokes Challenge Cup sixth-round tie last Friday.
It means he will miss Saturday's Grand-Final re-match with Castleford in Newcastle.
Winger Faraimo, who was sent off for the second time this season in Hull's 38-20 win at Featherstone for a high tackle, has received a two-match penalty notice, ruling him out of Sunday's Hull derby at St James' Park and the Black and Whites' trip to Warrington in Super League the following week.
Team-mate Josh Griffin, one of six players sin-binned during the sixth-round tie last Thursday, was cleared to play at the Magic Weekend after being charged with a minor grade A offence of punching.
Hull KR forward Danny Tickle can also play in the derby after his dismissal for punching against Wigan on Sunday was adjudged to be a grade A offence.
Forward Amor will have to sit out Saturday's opening game against Widnes after receiving a one-match penalty notice for a grade B dangerous tackle in Saints' cup win at Castleford.
Meanwhile, Featherstone centre Misi Taulapapa has been given a two-match penalty notice for a tackle off the ball during the Hull cup-tie.
Taulapapa avoided a yellow card for the offence but was charged by the Rugby Football League's match-review panel, which also gave Rovers forward Gareth Hock a one-match ban for punching.
Toronto forward Andrew Dixon, who was sent off for punching during his side's 66-10 defeat at Warrington, avoided a ban after the panel deemed the offence to be at the lowest end of the tariff.
Leigh prop Jamie Acton was given a caution for a dangerous tackle in his side's 22-10 win over Salford.
