Jack Cole has been named at five-eighth for Penrith's preliminary final against Newcastle on Sunday, though Jack Cogger is increasingly likely to start instead.
Cogger's stronger kicking game could prove important, according to the report.
The Panthers have covered the fencing around their training ground with black tarpaulins to prevent details reaching the Knights.
Nathan Cleary is expected to play despite being short of full fitness.
He injured his foot against the Roosters two weeks ago.
