Sydney Roosters player Sonny Bill Williams will miss two NRL matches after opting to enter an early guilty plea.

The NRL Match Review Committee charged Sonny with a grade 3 carless high tackle following the Roosters round 20 match against the Newcastle Knights last Sunday.

The decision to not challenge the charge will mean that the second-rower will return for the Roosters clash against the Wests Tigers in Round 23 at Allianz Stadium.
