Carlton coach Michael Voss has delivered an impassioned plea to the AFL community in the wake of receiving threatening messages.

The AFL, which is currently investigating the messages believed to be sent through the MCG's anti-social hotline service during Friday's loss to Collingwood, is considering deploying extra security messages to Voss and staff at the club as news came to light of a "heinous and inappropriate" threat.

The message, directed at Voss, is reportedly in reference to a "brutal end to his life", but is currently not being deemed as a credible death warning.

Herald Sun's Jay Clark revealed that the Blues had sent the threat to the AFL last week, and is now in the hands of the league's integrity department under investigation.

"Under siege, Carlton coach Michael Voss has reportedly received a heinous and inappropriate threat," a report from Channel 7 said.

"It is understood the message references a brutal end to his life. Although the message is not currently being treated as a credible threat, the AFL is considering extra security for Voss and other Carlton staff.

"The club denounced the vile language used in the message."

Voss fronted the media on Wednesday morning in preparation for the club's battle with Brisbane at Marvel Stadium on Thursday, and produced a passionate and reflective response to the threats.

"You go into a little bit of reflection mode through these weeks," Voss said.

"I remember as a four-year-old following my dad around and spending time in the sheds; he was captain-coach of everything, and you remember those moments really fondly.

"I always felt like football made you feel like you belong, and that's what football clubs are all about. You have a sense of belonging, it's about families, about communities. It's about bringing people together. I also remember as a 12-year-old at Morningside Football Club and having a brand-new footy โ€ฆ it was like the best gift I ever got, it was my first brand-new Sherrin. I used to smell it and always have it in my hands. It sort of really inspired me to ultimately follow my dreams, and that was really impactful on me.

"And then I've also seen the dark side of football, where we blame, we become victims, and it's this environment where things are quite toxic. We think by showing passion is about anger, and it's not about that at all.

"So when you see both, it's what you choose for me. So when I turn up for football and I turn up on the weekend, I look at that four-year-old and think about what families are and communities and how we bring people together and what we want our environment to be โ€“ and that's what it's supposed to be about. It's about bringing people together. So that is extremely important to me.

"And it's also about the 12-year-old who you want to inspire that next generation.

"So when I look across the fence, I see the 12-year-olds and I see the 14-year-olds with aspirations to be able to do this. And so the inspiration for me is about inspiring the next generation and leaving a lasting impact on what that looks like.

"So when you turn up on the weekend and I do what I do, I do that for Carlton and I do that for the next kid that's going to be playing in the Carlton Football Club jumper. I do it so our football club can be have this sustained success that we're all craving for.

"But there's a way we need to behave and there's a way we need to go about it โ€“ and when things are tough, you've got to show that support the right way. Not the wrong way.

"Now, if that's a measure for some people on what it should look like, then I'm sorry you don't belong here.

"We'll move on and we'll make sure we continue to bring a supporter base that will support in the good times and it will support in the bad, and we'll continue to support our people to be able to do that.

"So for me, the conversation doesn't need to be anything other than that. And it won't be for the next six, seven weeks as well. I get asked about different things, about pressure of the game and my job and what the future looks like โ€“ well, ultimately I only need to look across the fence about what inspires me every single day. We want to be the best version of ourselves, and that's how we're going to do it."

Voss was asked how he reacted to the threat, saying he was "dismissive at first", but acknowledged that it's "completely unacceptable".

"There's a flow-on effect," Voss added.

"The first thing you always think about is the person beside you, or the family member or the team. Because, as a result of what I do, you appreciate there's an element of scrutiny that comes with that.

"But then there's a part that's completely unacceptable, and I think we can all agree that part is unacceptable. And we don't tolerate that as an industry."

The message follows a fortnight after the Blues' headquarters were targeted by vandals who painted graffiti on the walls at Ikon Park last month, declaring that Voss, along with list manager Nick Austin, GM of Football Brad Lloyd and the Board be sacked.

Carlton had aspirations of top-four placings but has since slumped to 12th, claiming six victories from 16 starts.

The last three weeks have yielded disappointing results, with damning losses to North Melbourne, Port Adelaide and Collingwood, with Brisbane to come this Thursday.

Voss is contracted for 2026, but incoming CEO Graham Wright is reportedly set to assess all arms of the club, and could make wholesale changes like he did during his time at Hawthorn and the Pies.
