Alex Twal avoided suspension, while Wests Tigers lose Doueihi and Fainu. South's Fifita and Raiders' Pattie received bans for separate incidents in recent matches.
Alex Twal has escaped suspension for his uncharacteristic slap, but Wests Tigers are set to lose playmakers Adam Doueihi and Latu Fainu as they fight to keep their mathematical NRL finals hopes alive.
The bans come on a busy Sunday for the match review committee, which has handed South Sydney's David Fifita a one-game ban for kicking Hudson Young.
Fifita struck the Canberra second-rower in the head as he attempted to regain his footing following a tackle in the Rabbitohs' 32-24 loss on Saturday.
The Souths wrecking ball was not penalised on field, but will miss the round-21 clash with Melbourne if he pleads guilty to grade-two dangerous contact.
