Port Adelaide president David Koch has blasted the AFL over the Sam Powell-Pepper investigation, saying the player was railroaded.

Koch also says Powell-Pepper is a victim as the AFL attempts to rebuild its reputation with women following the resignations of key league executives Simon Lethlean and Richard Simkiss.

The midfielder has already sat out two games while the investigation into his drunken nightclub incident ran its course.

On Wednesday, the AFL announced Powell-Pepper would be suspended for three matches, which rules him out of Saturday's clash with North Melbourne.

The AFL said Powell-Pepper "engaged in inappropriate behaviour that is unbecoming for an AFL player by being intoxicated in a public place and by making inappropriate contact with a female".

Koch accused the head of the AFL integrity unit of not looking at all video relating to the incident, although Power CEO Keith Thomas said later in the day the league had viewed the footage.

"The whole respect and responsibility policy leaves the clubs in the dark. They take complete control. I issued them a grievance notice before they would start talking sense," Koch said in a statement to Triple M radio.

"My biggest issue was they are railroading a kid and trying to rebuild their reputation with women because of the misdemeanours of their own former executives.

"In Sam Powell-Pepper's case, a woman anonymously made these claims, did not press charges with police - which we were happy for her to do. We have vision of the entire night and the head of the integrity unit refused to see it.

"I'm putting it on the agenda at the next presidents' meeting."

Last year, Lethlean and Simkiss resigned because of affairs with junior colleagues.

Thomas refused to publicly release video footage of the nightclub incident involving Powell-Pepper, while insisting it showed "a huge discrepancy" between media reports and what actually occurred.

"That touching was a long, long way away from sexual assault," Thomas said on Thursday.

Thomas criticised the initial reporting of the incident by the Seven Network, where Koch coincidentally works as a presenter.

"It is very, very disappointing, it created a environment with difficulty to achieve fairness," he said.

Thomas said any accusation of sexual assault "can leave a stain on someone's life forever".

He said the Power were reserving their rights in terms of Seven.

"We think this has been way overplayed," Thomas said.

"Channel Seven Adelaide set the tone for the investigation and we'll be discussing that with them."

Collingwood president Eddie McGuire said there was a broader issue of growing discontent among the clubs about how the AFL treated them.

"The clubs are getting sick of getting treated like franchises," McGuire told Triple M.

"The AFL Commission was brought into place to act on behalf of clubs.

"There's a very strong feeling that the clubs are there as a necessary impediment to the AFL hierarchy - that's not Gil McLachlan, that's the levels underneath (him).

"It has (been) building for a long time ... the pendulum swings too far and the pendulum has to come back."
