Brett Morris is set to make a landmark appearance as the NRL Finals kick-off with a heavyweight clash between Sydney Roosters and South Sydney Rabbitohs.

Friday's match between the sides, who finished second and third respectively in the regular season, will be the first Finals game to be played at the Sydney Cricket Ground since the 1983 Grand Final.

Parramatta Eels won on that occasion and they round off the first round of Finals fixtures against the Brisbane Broncos on Sunday.

Minor premiers Melbourne Storm are in action on Saturday, taking on Canberra Raiders, before Manly Sea Eagles host Cronulla-Sutherland Sharks.
