La Rochelle lock Jone Qovu Nailiko has been hit with a two-week suspension for punching Richard Hibbard.
The incident occurred in the 54th minute of La Rochelle's Challenge Cup semifinal with Gloucester and went unpunished at the time.
He was since cited and the disciplinary committee deemed it a red-card offence, but on the low end of the sanctions.
The two-week suspension means he is free to play again on May 8.
