SOUTH Australian police have cleared Hawthorn coach Alastair Clarkson of any wrongdoing in his clash with a drunken AFL fan in Adelaide.

Clarkson clashed with a fan while walking back to his Adelaide hotel following Hawthorn's defeat to Port Adelaide on Anzac Day.

"It has been determined that no further action will be taken by South Australia Police. SA Police consider this matter to be finalised," SA Police said in a statement on Wednesday.

Video taken of the incident showed Clarkson push a man by the throat.

Clarkson said the time the man had been goading him as he walked back to the team hotel.

"Having been confronted and threatened by a group of intoxicated men and after politely asking several times for some space, I regret that I pushed away one particular individual," Clarkson said at the time.

"While the behaviour of the group was antagonistic, aggressive and completely unwarranted, I wish that I had continued to walk away and removed myself from the situation."

AFL football operations manager Mark Evans described the incident as regrettable, adding the league would await the police investigation outcome before taking any action.

The incident moved the AFL to insist all players and team personnel travel from AFL venues to team hotels by bus only.

The League is also waiting on Tasmanian police to conclude their investigation into an alleged assault by North Melbourne coach Brad Scott.

A security guard alleged Scott assaulted him during the Kangaroos' round six clash against Richmond at Blundstone Arena.

Speaking to Melbourne radio station SEN on Tuesday night, AFL football operations manager Mark Evans said he understood both police forces had gathered what was required to conclude their investigations.

"I received an update from our integrity guys last week to say they felt the police in the two states had collected the information they needed and just needed to finalise it at their end," Evans said.

"I haven't heard whether that's occurred."
