Toulouse winger Yoann Huget has received a citing commissioner warning following his dive against Bath on Sunday.
The French international went down theatrically during an altercation with Horacio Agulla during the loss, and has been warned under Law 10.4(m) for an act contrary to good sportsmanship.
Huget came in for heavy criticism following the incident, and apologised for his actions the following day.
Harlequins winger Tom Williams also received a citing commissioner warning for his dangerous tackle on Alapati Leuia during the home defeat to Wasps.
Bath winger Matt Banahan escaped punishment, however, for his high tackle on Jean-Marc Doussain during the Bath win in France.
Players who receive three citing commissioner warnings or yellow cards, or a combination of the two, will have to face a disciplinary hearing.
