South Sydney Rabbitohs forward Jason Clark has been ruled out of the Club's Preliminary Final match against the Sydney Roosters on Saturday 22 September at Allianz Stadium.

Clark rolled his ankle during training yesterday and a decision was made this morning to rule him out of the game.

Junior Tatola will be named as Clark's replacement as confirmed by Head Coach Anthony Seibold in this morning's media session.

The Rabbitohs' 19-man squad will be released at 7.40pm tonight.
