The hearing took place in the Ulster Branch offices in Ravenhill, Belfast at 4pm today (Tuesday). The hearing was chaired by Hugh Logan and he was assisted by Stephen Hilditch and Ian McIlrath.
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 ban rules Mafi out of Munster's opening two Heineken Cup games against London Irish and Toulon, as well as their next three Magners League fixtures.
The player is free to appeal the decision.
