Justin Tipuric has been suspended for three weeks for a dangerous tip tackle in the Ospreys' RaboDirect win in Munster on 8 October.
The flanker was sin-binned for the tackle on fly-half Ian Keatley in the 51st minute of the 17-13 victory.
The ban is similar to the one Sam Warburton received for his dangerous tackle for Wales against France.
And the committee believed Tipuric's tackle warranted a red rather than yellow card.
But having weighed up the video evidence and listened to the player's explanation the committee considered the offence to be at the low end of the IRB scale of offending.
And, in imposing the suspension, the committee recognised the player's co-operation at the hearing and that the Ospreys had not selected him from last Saturday's LV= Cup match against Exeter Chiefs.
Tipuric is free to resume playing on 31 October and has the right of appeal.
At the same disciplinary hearing in Edinburgh Munster prop BJ Botha was cleared of foul play, having been cited by the independent citing commissioner for striking an Ospreys player on the head.
