from the RFC site:
With the Tigers coming off a six-goal win over Essendon,
Wallace said changes were unlikely, leaving Kane Pettifer in the side and Greg Tivendale out.
"I was really pleased with him (Pettifer) – he was out leading goal-assist player on the evening, so he did his job well, and he had three tackles in the game.
"[Tivendale] is playing some fantastic footy in the reserves. We haven't made any bold statements about our players – and won't make any – if they play well enough, and there's an opening in the senior lineup, they'll get opportunity.
