Stade Francais player Jerome Fillol has received a 14-week ban for spitting in Bath scrum-half Peter Stringer's face.
The first-half incident happened during last Saturday's Amlin Challenge Cup quarter-final between the clubs and resulted in Stade number nine Fillol being cited.
Fillol admitted a charge of committing an act contrary to good sportsmanship when he appeared at an independent disciplinary hearing in Dublin on Thursday.
Fillol's suspension will take into account the closed season, covering a 10-week period from April 6 until June 16 and then another four weeks between July 15 and August 11.
Independent judicial officer, England's Anthony Davis, found Fillol had been guilty of "an intentional, deliberate and grave act".
Davis decided the offence warranted a top-end entry point in terms of punishment and considered 26 weeks as his base before applying 12 weeks' mitigation.
"The judicial officer identified no aggravating factors," European Rugby Cup said in a statement. "And after taking into account compelling mitigating factors, which included the genuine remorse expressed by the player at the hearing, as well as his exemplary record and strong character references, the judicial officer applied mitigation of 12 weeks, before imposing a sanction of 14 weeks."
A citing complaint against Fillol's Stade team-mate Rabah Slimani was upheld after he tackled Bath wing Nick Abendanon in the air.
But Davis decided that Slimani, who was sin-binned following the incident, did not warrant any period of suspension and he is free to continue playing.
However, Perpignan's former Wasps forward Daniel Leo collected a one-week ban after he was sent off for striking Toulouse player Christopher Tolofua with his arm during Perpignan's Amlin quarter-final success last Friday.
