The Scotland player, Fraser Brown, was cleared to play after he appeared before an independent Disciplinary Committee.
Brown was cited by an independent Citing Commissioner for dangerously tackling an opposition player, during the Six Nations match between England and Scotland at Twickenham on Saturday.
The player accepted that he had committed an act of foul play but argued that it had not warranted a red card.
The Disciplinary Committee, chaired by Jean-Philippe Lachaume (France), alongside Rhian Williams (Wales) and David Martin (Ireland), having reviewed footage of the incident and all other evidence, as well as hearing submissions and testimony from the player and his representatives, considered the tackle to have been dangerous, and therefore contrary to Law 10.4(e).
The Disciplinary Committee, however, found that the act of foul play would have not have warranted a red card, and so the citing complaint was not upheld and no sanction was imposed.
(The Disciplinary Committee also considered whether or not the player, in carrying out the tackle, had infringed Law 10.4(j), but found that not all of the necessary elements for foul play under that law had been present).
The player is therefore able to resume playing immediately.
