Scarlets have launched an investigation into claims of racist chanting during their Champions Cup quarter-final win over La Rochelle.
Allegations of racist abuse aimed at La Rochelle players surfaced on social media after the Scarlets' 29-17 win on Good Friday.
And the Scarlets have confirmed they will now look into the matter.
"We have a proud history of being a family club and events such as this are completely unacceptable," said a Scarlets spokesperson.
"An investigation will be undertaken to understand the full facts and background of the incident before commenting further."
The Scarlets' victory set up a semi-final showdown with Leinster at Dublin's Aviva Stadium, to be played on the weekend of April 21 and 22.
