South Sydney have been dealt a blow with influential hooker Issac Luke facing up to two weeks on the sideline for a dangerous throw.

The New Zealand Test rake was charged by the NRL match review committee with a grade-one dangerous throw on Penrith’s Tyrone Peachey.

With the Rabbitohs having the bye next weekend, he will only miss his side’s clash with St George Illawarra in a fortnight with an early guilty plea.

But he will sit out two rounds should he unsuccessfully defend the charge at the NRL judiciary.

The Rabbitohs have a handy replacement for Warriors-bound Luke in Cameron McInnes, who is being groomed to take over the Souths No.9 jersey next year.

Luke has been one of the side’s best since being relegated to the bench earlier in the season.

Cronulla back-rower Chris Heighington will miss one match after he was charged with a grade one dangerous throw on Manly’s Josh Starling.
