Ulster head coach Dan McFarland has backed the province's stance to "robustly investigate any complaints" after Racing 92 player Simon Zebo tweeted that he was subject to unacceptable comments from some fans in the Kingspan Stadium crowd during last Saturday's Champions Cup clash.
The former Munster man tweeted after the game: "I hope my ears deceived me with some comments directed my way from the crowd. #NotOn Django wins in the end."
Mr McFarland appealed for any information that would help shed more light on the alleged incident.
He said: "We are aware of Simon's social media postings and if that is true it's totally unacceptable. As an organisation we put inclusivity right at the forefront of who we are - that's across everything.
"When something like this happens it is taken extremely serious and will be dealt with. If there is anybody out there who knows what happened and can give information on that, we want to know.
Dan McFarland spoke to Q Radio:
Racing 92 released a statement regarding what they said were "racist insults" directed at Zebo
It read: "Racing 92 strongly condemns the racist insults that Simon Zebo was targeted with on Saturday during the European Cup game between this club and Ulster Rugby at Kingspan Stadium in Belfast.
"Racism has no place in rugby, in which the values of solidarity and togetherness are the exact opposite of any forms of discrimination.
"Racing, however, does not wish to stigmatise Ulster Rugby as a whole.
The insults suffered by Simon Zebo are the actions of only one or two individuals and have been condemned by many Ulster fans who have shown their support for Simon."
