Cornes was investigated by the match review panel for an incident in Sunday's game at Skilled Stadium in which he fell to the ground after receiving apparent contact from Geelong's Corey Enright, but he was not charged under the AFL's new anti-staging rule, which carries a fine of up to $2400 for repeat offenders.
A 2009 incident involving Cornes was one of four which illustrated the anti-staging section of the Laws of the Game DVD issued to clubs at the start of the year and it has been reported he has been put on notice by the match review panel.
On Wednesday, Rodan said the Port Adelaide tagger played within the rules of the game.
"I don't think Kane stages. I think he competes very hard and he's got a tough gig each week playing on the best players in the AFL, so he does a really good job," Rodan said.
"It's only a matter of time before they [the match review panel] get someone. It's hard to put it on a player [to say] that they stage. A lot of players go out there to win the footy and do those hard types of things, but maybe they will catch someone out."
Rodan made a successful return to AFL against the Cats last weekend, just 16 weeks after having LARS surgery to repair a torn anterior cruciate ligament in his knee.
The Power midfielder picked up 15 touches on Sunday and said he was hoping to build on his promising performance against St Kilda this week.
"I got a quick, early touch on Sunday which helped the confidence and soon after I got a hit as well. I got two good things that I think I wanted early in the game and then I was off and running," Rodan said.
"I'm very confident at the moment and hopefully in the next few weeks I can play some good football and the team can get a win."
Sydney Swans defender Nick Malceski became the first AFL player to have the revolutionary LARS procedure when he injured his knee in a pre-season game in February, 2008.
Incredibly Malceski returned to the field in 12 weeks, but he experienced a drop in form soon after.
Rodan said he'd spoken to Malceski about his downturn and was confident he wouldn't experience the same lull in his comeback from the same injury.
"I spoke to Nick about that. We didn't hear much about him soon after he made his return, but he pretty much said he was down on form and that it had nothing to do with the knee," Rodan said.
"Nick's been a great support and also Brad Fisher as well, who he's also been speaking with over the last few weeks. Apparently Brad's travelling well and is starting to run, so guys who have LARS form tight-knit community. It's always good to see guys like Nick who have been through it come through the other end and play some good footy."
The Power appear set to ring the changes after the 95-point loss to Geelong, with veteran Josh Carr, midfielder Hamish Hartlett, ruckman Matthew Lobbe and injured pair Jay Schulz (knee) and Paul Stewart (hip) all in contention.
Rodan said he expected several changes to the side this week.
"A lot of guys went back and played really well in the SANFL, so they've put their hands up. I know Choco will be looking at them."
