Leinster, Bath and Tigers all had players in the dock this week following citings from domestic action.
Leinster Head Coach Michael Chieka must wait till Wednesday evening to hear whether Jonathan Sexton will be available for selection for their quarter-final against Quins, when a Celtic Rugby Disciplinary Committee meets to consider a citing against the outside-half for allegedly kicking Munster centre Lifeimi Mafi in Saturday's Magners League clash.
In other disciplinary news Bath number 10 Butch James was cleared on Tuesday of a charge of stamping on Riki Flutey during their mid-week game against London Wasps by an Rugby Football Union Disciplinary Panel.
Their quarter-final opponents Leicester were not so lucky as the Tigers must plan without Julian White who earlier received a two week ban for punching during the Tigers' Premiership game against Sale Sharks.
