Tofiga stomped on the head of Toko forward Adam Knight late in the game. Tofiga was not sent off but was taken off the field by Taieri management.
Taieri club captain Mike Casey said it was a bad incident, and Tofiga had shown a lot of remorse at the hearing. Mr Casey said it was completely out of character for Tofiga, and the player could not explain why he did it.
The player did not wish to comment further.
Knight, who only played the final quarter of the game, said he was satisfied with the way the Taieri club had handled the incident.
A melee broke out late in the game when a Taieri player objected to being cleaned out at the breakdown, Knight said.
The referee blew his whistle and the fighting stopped. Within a couple of seconds, Knight's head was trampled on by Tofiga.
Knight was taken from the field and given seven stitches for a cut of about 10cm.
He hoped to get the stitches out next week.
Knight, a former Otago sevens player, normally plays rugby for the Southern club, and was playing for Toko only because Bloxham was his uncle and Knight wanted to play in the match.
He spoke to Tofiga after the match and at the hearing on Wednesday, and accepted his apology.
With the premier 2 season lasting 18 weeks, Tofiga's ban will run into next year.
Otago Rugby Football Union general manager Richard Kinley did not wish to comment on the incident.
He was waiting for the official report and could not make a comment until he received it, he said.
