AFL club Hawthorn are in behaviour-related damage control, with coach Alastair Clarkson facing allegations he abused an official at his son’s under-nines football carnival.

Clarkson has admitted using expletives to an adult official while a runner in a junior match on Sunday.

It came the day after Clarkson’s angry outburst when he put his hand through a wall in the MCG coaches’ box during the Hawks’ win over Collingwood on Saturday.

Clarkson has agreed to pay for the repairs.

The Hawks have also confirmed police are investigating an incident in which fringe player Jarrad Boumann injured his hand in an altercation early on Sunday morning after leaving a nightclub.

Boumann has claimed he was acting in self-defence.

And the club has penalised superstar forward Lance Franklin over the speeding incident last week which cost him his driver’s licence.

Franklin must make a $1000 donation to a road safety charity, undergo driver education, and organise a presentation from an outside body to all Hawthorn players on responsible conduct on the roads.

Clarkson has apologised for the language used in his exchange with the official – an incident now under investigation by the South Metro Junior Football League.

Clarkson says he was attempting to re-organise the players when both teams began to kick to the same end, and repeatedly tried to explain the situation to an off-field league official when he was instructed to leave the ground.

“During the conversation with the league official, I used a couple of expletives and I apologise to the official for the language used,” Clarkson said.

“I was only trying to re-organise the players into their correct positions and certainly didn’t intend for this to become an issue for the official, the league, or the two teams.”

Boumann told the Hawks he was leaving a nightclub with a friend and looking for a taxi when a verbal exchange with a group of men escalated.

He said he acted in self defence after being repeatedly kicked by a number of people while he was on the ground, injuring his hand during the fracas.

Hawks chief executive Stuart Fox has expressed his disappointment in the off-field distractions, especially considering the club have been in red-hot on-field form to cement themselves premiership favourites.

“In a week in which we should be proud of our football team’s performances we are disappointed to be in this position,” Fox said.

“To have four matters requiring management is unsatisfactory, as is the unnecessary distraction indiscretions such as these place on our football club.”

Fox said the club would “resolve each issue appropriately and in accordance with Hawthorn’s culture and values”.

Senior Hawthorn player Sam Mitchell said Franklin, who has been banned from driving for six months after being clocked driving at 90km/h in a 50km/h zone last week, was remorseful over his incident.

“He’s not someone who takes that sort of stuff lightly. He realises the impact he has on people in the community,” Mitchell said on Monday.

“He’s pretty flat about it so … I’d be pretty confident just from a personal point of view that nothing like that will happen again.”

Franklin, who is recovering from a hamstring injury, has earmarked the clash with premiers Geelong in a fortnight as his comeback game.

He trained lightly on Monday.
