Boudjellal told French radio RMC that Savea has been released and is "free to do what he wants" despite the former All Black having a year remaining on his contract.
"I'm going to ask for a DNA test. They must have swapped him on the plane [when he joined from Hurricanes]. If I were him I would apologise and go back to my home country.
"I've told him that he was free to go and wasn't welcome at Toulon anymore," said Boudjellal
