Parramatta back-rower Manu Ma'u is in danger of missing his side's Round 21 clash with Wests Tigers, one of two players cited by the NRL match review committee from the three Saturday fixtures in Round 20 of the NRL Telstra Premiership.

Ma'u was charged with a grade one dangerous throw on Titans halfback Ash Taylor, and two prior non-similar offences in the past two years haven't helped his cause, with an early guilty plea still resulting in a one-match ban.

Warriors forward Bunty Afoa was also slapped with a grade one dangerous contact – head/neck charge, but will escape suspension with an early guilty plea.
