A three-member panel believed it had violated law 9.12 (no player… with any part of the arm, shoulder, head or knee beating).
France won 35-16 to win the six-nation title.
After the game, Scottish coach Gregor Townsend asked why Maovaca was able to return to the pitch, with officials at the time they saw the challenge that they had no great strength.
But Townsend pointed out that power has nothing to do with it, because it was an accident outside the ball, not the wrong adhesive.
Maovaca will feature in Toulouse against Bordeaux and Pao, as well as the 16 champions in the Champions League with sales.
