London Irish centre Shontayne Hape has been banned for four weeks by the body which organises European club rugby.
Hape, 30, was cited for a dangerous tackle on Edinburgh back row David Denton last week and has now been found guilty following a hearing in Dublin.
Edinburgh lock Sean Cox has also been banned for a week following an incident in the same Heineken Cup match.
Cox was found guilty of striking Hape during the second half following a running battle with the England player.
Hape becomes the second London Irish player to be banned, with fellow England back Delon Armitage currently serving a five-week suspension.
The Exiles next face Cardiff Blues in Wales, while Edinburgh host Paris side Racing Metro 92, both matches taking place on Friday.
