St George-Illawarra hooker Mitch Rein is facing one week on the sidelines after being charged with a dangerous throw in his side’s NRL loss to the Sydney Roosters on Monday night.

Rein was only slapped with a grade one dangerous throw on Roosters second-rower Boyd Cordner in the first half but will miss a game due to a previous offence unless he fights the charge and wins.

The Dragons next take on Parramatta on Saturday night.
