Reds prop Sef Fa'agase will be free to face the Highlanders in a fortnight, suspended for one week for kneeing.
Fa'agase was given an off-field red card by the SANZAAR citing commissioner after kneeing NSW Waratahs hooker Hugh Roach in the head as a scrum collapsed.
The 24-year-old was the second Reds player to collect Roach, who was in the middle of the scrum on the ground, but went unpunished in the match.
Fa'agase's front row teammate Andrew Ready, the first player to connect with Roach was yellow carded for the incident.
The SANZAAR judiciary officer Robert Stelzner considered intent, Faagase's guilty plea iand his clean record in the decision.
"I considered the offending to be at the low end. I accepted the players admission that he did not intend to deliberately strike his opponent, the fact that there was no great force applied and the fact that his opponent was not injured," he said in a statement.
"The player’s admission, his show of remorse for the offending and his clean record entitled him to a 50% reduction in sanction, which would have resulted in a two week suspension if it were rounded up.
"The offending was however such that I considered two weeks to be wholly disproportionate with the level of offending."
With Reds captain James Slipper set to return to the starting loosehead spot after the Reds' bye, the club argued Fa'agase would have played in a Queensland Premier Grade match for University this weekend.
