Tupou was cited by SANZAAR over a tackle on winger Craig Barry in the ninth minute of their 25-19 loss to the Stormers that went unpunished at the time.
He has been charged with contravening law 9.13: 'A player must not tackle an opponent early, late or dangerously'.
SANZAAR's foul play review committee looked at the incident earlier this week, scheduling a hearing for 5pm Tuesday AEDT.
