Phoenix Crossland's suspension puts him among players who have missed grand finals after disciplinary bans.
Cameron Smith sat out Melbourne's 2008 decider, Latrell Mitchell missed South Sydney's 2021 final, and Steve Roach and Arthur Beetson were absent for Balmain in 1988 and 1969.
A judiciary hearing on Tuesday night banned the 26-year-old Newcastle hooker for four matches.
The penalty rules Crossland out of Sunday's grand final against the Sydney Roosters and the start of New Zealand's World Cup campaign.
His suspension followed a hip-drop tackle in Sunday's preliminary final that twisted Nathan Cleary's left leg and broke it.
Crossland was sent off during the first half, and later described the fallout as "the worst couple of days of my life".
