Dundalk have condemned racist abuse directed at their players after the 3-1 Europa League defeat to Rapid Vienna on Thursday evening.
Chris Shields scored Dundalk's goal at the Aviva Stadium after Nathan Oduwa's earlier spot-kick went wide.
A statement from the club read: "Dundalk FC has been made aware of some vile comments directed at members of our squad on social media.
Racism and discrimination is a stain on football and society as a whole and everyone at the club is disgusted by – and utterly condemns – the comments that were made.
The individuals who expressed these views do not represent the values of our club and we will take the strongest course of action available to us.
Dundalk FC has zero-tolerance of any form of racism or discrimination and we will do whatever is possible to protect our players and supporters from such abuse"
