Stade Francais duo Laurent Sempere and Paul Gabrillagues have been cited along with Leicester Tigers' Tom Youngs following Sunday's feisty European Rugby Champions Cup clash at Stade Jean Bouin.
Sempere and Gabrillagues could face lengthy bans after being reported for allegedly making contact around the eyes of Marcos Ayerza and Dan Cole respectively in Stade's 36-21 victory.
There was also a citing complaint over hooker Youngs, who was sent to the sin-bin during the second half following an incident in which he is alleged to have punched prop Rabah Slimani.
Victory for Top 14 champions Stade ensured they will face the Tigers at Welford Road in the quarter-finals in April.
Scarlets second row Maselino Paulino was also cited on Tuesday for allegedly striking Northampton Saints' England international Courtney Lawes during the Premiership side's 22-10 Champions Cup win on Saturday.
