Harlequins prop Joe Marler has been suspended for two weeks after appearing to aim a kick at the head of Grenoble's Arnaud Heguy in Friday's 30-6 European Challenge Cup semi-final victory.
England forward Marler was playing his first game since serving a two-match ban for calling Wales' Samson Lee a "gypsy boy" during the Six Nations.
"A Disciplinary Committee consisting of Roger Morris (Wales), Chairman, Simon Thomas (Wales) and Kathrine Mackie (Scotland) heard evidence and submissions from Marler, who accepted that he had committed an act of foul play but who did not accept that the foul play warranted a red card, and from Richard Smith QC on behalf of Marler," read a European Professional Club Rugby (EPCR) statement.
"The Committee also heard evidence and submissions from the EPCR Disciplinary Officer, Liam McTiernan.
"In upholding the citing complaint, the Committee found that Marler had committed an act of foul play that warranted a red card. It determined that the offence was at the low end of World Rugby's sanctions and selected four weeks as the appropriate entry point.
"In deciding to disregard the player's recent suspension as it was of an entirely different nature, the Committee then reduced the sanction by two weeks - 50 per cent of the entry point - before imposing a suspension of two weeks."
Marler will miss Quins' Premiership fixtures against London Irish and Exeter Chiefs but will be available for the Challenge Cup final against Montpellier on May 13.
In addition, Wasps' Simon McIntyre has been suspended for the same period over a kick on Saracens second row Maro Itoje.
