A final decision will be made tomorrow or Saturday about whether Penrith skipper Craig Gower will play against the Sharks on Sunday.
"We'll train tomorrow afternoon and see how Gowie pulls up," coach John Lang said this afternoon. "We'll make a decision either straight after that or maybe wait until we see how he pulls up on Saturday.
"If this was a grand final there would be no doubt he would play, but we certainly won't be taking any risks at this stage of the season," John said.
Gower injured a knee in SOO1 but played on for nearly 20 minutes with the injury. The decision to bring him back this week was unexpected.
