Hodgman was given a red card for his hit on Highlanders replacement flanker James Lentjes.
Hodgman hit Lentjes high with his shoulder and left referee Brendon Pickerill with little option but to send him from the field.
Hodgman pleaded guilty to the act of foul play when he appeared in front of a judicial hearing.
The foul play merited a mid-range entry point of six weeks’ suspension but taking into account mitigating factors of the player’s good judicial record and guilty plea, it was reduced to three weeks.
He will miss games against the Crusaders and the Chiefs over the next two weeks and the final, should the Blues qualify.
Should they miss the final, the penalty may be lengthened to include the first game in the Super Rugby transtasman competition.
