Francois Louw has now been cited having allegedly made contact with the eyes of Marco Fuser, during Baths win over Treviso on Saturday.
Louw will attend an independent disciplinary hearing in London on Wednesday, with the incident alleged to have happened in the 77th minute of Bath’s 23-0 victory.
Should he be found guilty the South African flanker will be facing a lengthy spell on the sidelines.
Any contact with the eye area of another player brings about a suspension of between 12 to 52 weeks.
Fuser has also been cited, for supposedly biting the Springbok flanker, also in the 77th minute at the recreation grounds.
The only other player cited from Champions Cup action this weekend is Leicester back-row Mike Williams for allegedly making contact with the face area of Racing 92 centre Henry Chavany.
