High-profile former player manager Ricky Nixon has found himself embroiled in more controversy after apparently leaving a death threat on the phone of former Collingwood player Guy Richards.

In phone recordings given to BackPageLead, Nixon can be heard identifying himself and then, in one of the calls, making the threat to Richards, whom he blames for having a role in ending his relationship with 27-year-old Tegan Gould.

Earlier this year, Nixon struck up a relationship with Gould, with the couple claiming that they were in love despite reported opposition from Gould's family.

Richards is a friend of Gould's and is also thought to have advised her against seeing Nixon.

Nixon allegedly left three messages on Richards' phone. In the first, on November 14, he questions Richards on the content of his communication with his then-partner Gould, before warning the ex-Pie "it would not be in his best interest" to call her again.

The second message portrays a seemingly more controlled Nixon, claiming that he wanted to "sort out" the situation that had arisen with Richards.

But, in the third, an agitated Nixon erupts, saying: "You just made the biggest mistake of your life, c***." In the same tirade, he makes the death threat towards the former Magpie, saying: "Contract out. You won't make it to Sunday".

Immediately afterwards, Richards seemed angered by Nixon's antics, and wanted the former agent to be held accountable and 'put in his place'.

On November 16, Richards wrote on his Facebook page: "u made a BIG boo boo Ricky...he is a massive germ!! he has stuffed up and needs to be put in his place"

Yet, later in the week, Richards seemed to change his tune regarding the threats, even making light of them on his Facebook page.

"The last supper with Ricky", he wrote on Saturday.

"It's ok, it's ok!! I'm still alive", he wrote a day later, when the supposed 'contract' was to have been taken out.

Ms Gould told the Herald Sun today that Nixon had struggled to deal with her friendship with the former Magpie.

"It's between them and hopefully they will just grow up - they are men - seriously grow up. We are just friends," she said.

Neither Richards nor Nixon was available for comment.

Nixon became the highest-profile AFL player manager in the 1990s when the company he established in 1994, Flying Start, quickly becoming the agent to some of the code's biggest names. He pioneered the Club 10 "super stable" concept, which included Gary Ablett Sr, Wayne Carey, Jason Dunstall, Tony Lockett and Garry Lyon and later Ben Cousins.

Yet it all came tumbling down for Nixon this year when he found himself at the centre of a scandal involving the 'St Kilda schoolgirl'.

Video emerged of the pair together in a hotel room but Nixon said he could not recall the events because he'd been heavily drugged without his knowledge. It was also alleged the teenager took illicit substances with Nixon, and that the two were involved in a sexual relationship. Nixon denied those claims.

At the time of the incident, The Herald Sun reported that police were investigating potential death threats made by Nixon towards the girl.

After the scandal broke earlier this year, Nixon was subsequently banned for two years from being a player agent by the AFLPA, and Flying Start collapsed.

He has since sold his business.
