The plot thickens.

European Professional Club Rugby (EPCR) has opened an investigation into the comments made by Toulon owner Mourad Boudjellal when he defended Mathieu Bastareaud following the French international’s homophobic remarks.

Bastareaud was caught on camera aiming a homophobic slur at flanker Sebastian Negri  during Toulon’s 36-0 Champions Cup victory against Benetton Treviso on Sunday before apologising on social media.

Boudjellal said he feared the “mormon side” of the EPCR after Bastareaud was cited.

“At no point did Mathieu Bastareaud make a judgement on the sexual orientation of the player in question,” Boudjellal told rugbyrama.fr.

“I am not homophobic but I have already called someone a faggot. It’s become customary, it’s the first thing that comes to mind in an altercation.”

“I am worried. What I fear is the mormon side of EPCR with the Welsh and the Irish,” 

An investigation has now been opened on the comments made by the outspoken owner.

“EPCR is currently investigating comments attributed to RC Toulon president Mourad Boudjellal,” an EPCR statement read.

“If EPCR feels that these comments are inappropriate… Mr Boudjellal could face disciplinary action.”
