Hull FC forward pair Mickey Paea and Andre Savelio will serve one-match suspensions for raising the knees and tripping.
The Black and Whites won 23-16 at Salford Red Devils on Sunday thanks to a Josh Griffin hat-trick, but Lee Radford has been dealt a blow to his forward pack.
Paea received a one-match ban for a Grade A raising of the knee charge, while Savelio picked up a one-match penalty notice for a Grade B trip in their win at Salford.
Former Tonga international Paea was also charged with raising the knee a second time but he has not picked up a suspension on that occasion. Salford forward Gil Dudson was also cautioned for raising the knee.
FC hooker Danny Houghton escaped a ban for a Grade A trip, while Carlos Tuimavave was also cautioned for tripping.
Paea and Savelio will miss Saturday’s trip to Catalans Dragons.
