The Rabbitohs have enacted an option in Grevsmuhl’s contract which extends the 22-year-old’s deal for a further season, following a quality rookie season in the top grade where he played 22 NRL games and played part in the Indigenous All Stars, World Club Challenge and Auckland Nines victories.

The club also announced the signing of back-rower Cameron Murray who was a standout in the Rabbitohs' SG Ball and played in the Australian Schoolboys in 2015.
