VIDEO: France lock gives fans the middle finger
Vahaamahina will face a disciplinary panel, the LNR confirmed, after being red-carded for punching an opponent during a 17-27 defeat to Agen on Saturday.
As he left the pitch, the 26-year-old Noumea-born player defiantly responded to Agen fans by raising his middle finger.
Vahaamahina offered apologies afterwards via messages on his Twitter account, but a ban of more than a week could see him excluded from France's travelling party to New Zealand next month.
