Papali'i was shown a yellow card for his high shot on Crusaders first-five Richie Mo'unga during the Blues' 15-3 defeat in Christchurch on Saturday. That was upgraded to a red upon further review from the TMO.
Newshub reports on Tuesday, SANZAAR announced Papali'i will serve a three-week ban for the incident, ruling him out of their final stretch of the round-robin.
