Moscon admitted to using racially abusive language towards Frenchman Reza at the end of stage three of the race on Friday (April 28).

The 23-year-old, who was allowed to complete the race, which finished yesterday, is also facing a disciplinary hearing with senior management at Team Sky.

According to cyclingnews, Team Sky directeur sportif Nicolas Portal and Moscon visited FDJ and the French rider to apologise for the incident, which was accepted by Reza.

"This is something we're going to take seriously after the race," Portal told cyclingnews.

"In this sport we have all generations of bike riders and some really young bike riders. 

"It's our job to teach them the right way. 

"We've seen really bad behaviour in other sports, and this is really bad. 

"We explained this to Gianni and he understood."

In a statement posted on their media Twitter account, the UCI said: "The UCI expects everyone in its sport to respect the highest standards of ethics and conduct.

"Racial abuse has no place in cycling or any other sport and any such complaint will be investigated and sanctioned if substantiated."

Moscon could be banned for as long as six months as a result of the incident, which has sparked widespread condemnation.

It led to one member of the peloton - Reza's team-mate Sebastien Reichenbach - describing the culprit as a "disgrace to the sport".

He did not directly mention Moscon but his comments, made on Twitter, came on the day the incident took place.

"Shocked to hear idiots still using racist insults in the pro peloton," said Reichenbach.

Team Sky said they were taking the matter "extremely seriously".
