Garry Lyon has revealed he sent Billy Brownless an apology text message but never received a response from the former Geelong star.

Lyon opened up to Mike Sheahan in an in-depth interview this morning, explaining he hopes he can repair his friendship with Brownless.

"It was a text, yeah," Lyon said on SEN Breakfast.

“I spoke to Bill before this became public a year or so ago.

“Beyond that, it’s something for he and I to work through. We will do it. If he wants to talk about it publicly, then that’s his right. But I won’t be.”

Lyon said that he wasn't “jumping out of his skin" to talk to Billy about his relationship with Nicky (Brownless' ex-wife), which is still ongoing.

“Nicky and I are together and I am eternally grateful that she’s been able to support me through it,” he said.

“I was separated back in 2014, it’s hard enough to deal with separation, hard enough to deal with privately let alone publicly when you throw in a new relationship that lots of people frown upon, a person who was once married to a friend.”

Lyon also opened up about his battle with mental health issues, revealing he has been dealing with the illness since 2009.

“I sought professional help eight years ago and went through that process for about two weeks,” he said.

“I just wasn’t ready … I didn’t pursue it, to my detriment I have no doubt.”

Lyon will appear on SEN Radio's revamped breakfast program in 2017, alongside Hamish McLachlan and Tim Watson.
