Yoann Maestri has avoided a ban following an incident deemed to be "just short of warranting a red card" by the citing commissioner from Ireland's clash with France on Saturday.
The French forward has been issued with a Citing Commissioner Warning for using his shoulder to make contact with Ireland out-half Jonathan Sexton.
A statement from the RBS 6 Nations read: "A Citing Commissioner Warning has been issued to the French second row, Yoann Maestri, following an incident in the 13th minute of the match between France and Ireland on Saturday, 13 February 2016 in the RBS Six Nations Championship.
"The independent citing commissioner reported that Mr Maestri had used his shoulder in making contact with the Ireland outside-half, Johnny Sexton, which resulted in Mr Sexton being knocked off his feet.
"The citing commissioner concluded that Mr Maestri had infringed the World Rugby's laws of the game and that his actions fell 'just short of' warranting a red card. Mr Maestri has been informed of the Citing Commissioner Warning."
Future disciplinary action could follow should Maestri pick up two further warnings or yellow cards. In that case, a 'totting up' case would take place.
