Munster centre Lifeimi Mafi has been banned for seven weeks after being found guilty of a dangerous tackle on Leinster's Gordon D'Arcy during Saturday's Magners League derby clash between the two sides.
The Tongan born three-quarter was sin-binned following the incident in the 19th minute of the match at Dublin's Aviva Stadium, which Leinster won 13-9, and appeared at an IRFU disciplinary hearing at Ravenhill.
An IRFU statement read: "Having studied the match footage and heard all available evidence, the disciplinary panel found Mafi guilty under law 10.4 (e) for a dangerous tackle and decided that it was at the top end of entry for such an offence."
The statement continued: "The panel took into account the player's previous good disciplinary record before they imposed a sanction of seven weeks' suspension, up to and including Sunday, November 21."
The suspension means Mafi, who has the right to appeal, will miss Munster's Heineken Cup games against London Irish and Toulon as well as their next three Magners League fixtures.
