Loose forward Mafi will appear in Dunedin District Court on Monday, charged with injuring with intent to injure in an incident in South Dunedin.
It's a dismal postscript to the Rebels' bold, but unsuccessful attempt to secure a Super Rugby finals berth, when they lost 43-37 to the Highlanders on Saturday.
While police didn't name Mafi, Rugby Australia had earlier confirmed the Tongan-born Japanese international loose forward was being held in police custody.
