HAWTHORN forward Lance Franklin will miss this weekend's clash with Collingwood after having his challenge thrown out by the AFL tribunal on Tuesday night.

Franklin had been offered a one-match ban by the match review panel for his shepherd on Western Bulldog Jason Akermanis, but was not risking a lengthier suspension by challenging it.

However, he now carries 75 demerit points towards his future record.

A level one engaging in rough conduct offence, the incident was assessed as negligent, low impact and high contact.

Franklin was adamant that the decision would not change the way he approached his football.

"I didn't think there was too much in it," he said as he left AFL House.

"I found out after the game that I might be up, but I was very surprised that I was.

"I'm very disappointed that I'm not going to be out there this week with the boys, but it's only a week and I'll be back again North Melbourne, which will be good."

Hawthorn argued that Franklin had no reasonable alternative but to bump Akermanis, because its 196cm forward couldn't avoid contact and instead attempted to minimise the impact once he realised the Bulldog had disposed of the ball.

Caught in a classic sandwich, with Franklin coming in one direction and Rick Ladson from the other, Hawthorn said 177cm Akermanis had nowhere to go.

Counsel for the Hawk, Chris Townshend SC, made the point that after Akermanis disposed of the ball, Franklin was committed to the play and "he can't magically disappear from the scene".

The Hawks also contended that the difficulty with low impact cases was that they often existed because the player was doing all he could to minimise the impact.

The jury deliberated for 15 minutes before handing down the guilty verdict.

Football manager Mark Evans said the club was disappointed with the result, but indicated there would be no appeal.

"It's a sense of déjà vu, isn't it, to come here and come away with a disappointing result on this," he said.

"There were a lot of big hits and big tackles this week and we didn't think this was one of them.

"We thought Lance's actions were reasonable and we thought he had a pretty good chance of getting off, so it's a disappointing result.

"I think in a bumping situation it's difficult when you've got a tall guy and a short guy, but we always have to come back to whether we think the player acted reasonably, and we think Lance did."

Franklin's last trip to the tribunal came as a result of a similar incident against Richmond's Ben Cousins in round 21 last year, where he was banned for two games after initially appealing the suspension.
