Collingwood's Jaidyn Stephenson was handed a harsh penalty by the AFL for betting on Magpies matches.
He will be banned from 10 games, the remainder of the home away away season, and suspended for a further 12 as well as a $20,000 fine.
The harshness of the penalty is a warning from the league, enforcing their rules and showing that they have a zero tolerance towards the issue.
And so we've taken a look at other examples when sporting stars bet on their own team.
How does Stephenson's compare to the following five cases?
The former league MVP and star halfback for the Greenbay Packers was suspended for one-year in 1963 for betting on NFL and college football games. He claimed he was only better 50 to 100 dollars a game with friends, but NFL commissioner at the time, Pete Rozelle, banned him on the principle of the action.
"This sport (NFL) has grown so quickly and gained so much of the approval of the American public that the only way it can be hurt is through gambling. I considered this in reaching my decision," said Rozelle.
The NFL handed down multiple suspensions to other players that same year. Rozelle was later awarded the Sports Illustrated Sportsman of the Year award in that year for his actions on sports gambling.
In 2011, Health Shaw and Nick Maxwell shared inside information with family and friends that Maxwell, a defender, would be playing in the forward line for the next game and to place a bet on him for first goal.
The odds of this happening were 100-1 and Shaw, at a TAB, gave $10 to his friend to put the bet on for him. Maxwell's family also put on the same bet totalling up to $85.
When they were caught, Shaw was banned for 14 games, suspended for six, and fined $20,000 while Maxwell was fined $10,000.
"The rules state any information you give out is not to be used for gambling purposes. I never said in black and white you can't use that information to gamble," Maxwell said.
"It's not [my family members'] fault because I had never explained to them that situation. They had no idea. I never in my wildest dreams thought they would use this information to gamble."
In the game Shaw bet on, John McCarthy kicked the first goal.
West Tigers centre Tim Simona had his contract terminated and deregistered by the NRL after he had bet against his own team and kept charity proceedings for himself.
The exact details of his bets weren't released but it was said that there were "multiple" and that "they go back over a couple of years”. These bets included against the his own team in some cases.
The charity proceedings were for the sale of NRL jerseys sold on online auctions. It was his responsibility to pass the money on which he failed to do.
Because of this, NRL CEO Todd Greenberg said "[it is] very hard to imagine that Tim Simona will be registered with the NRL at any time in the future.”
Pete Rose was a star baseball player for the Cincinatti Reds between 1963 and 1978 and eventually the manager between 1964 and 1989. ESPN reported in 2007 that he betted "every night" while the manager of the club.
However, it later was revealed on Outside the Lines that he placed bets while in his playing career as well, something he denied when admitting to his time as a manger.
He placed bets on all major US sports, including his own. In a notebook found by Outside the Lines, he bet around $2,000 a game and once lost $5,500 on the Boston Celtics. His worst month, according to the notebook was when he lost $15,400 on one day in March.
Rose eventually received a lifetime ban for gambling in 1989. Due to his ban he isn't eligible to make the Hall of Fame, something he hopes he can do one day if reinstated.
He asked the new MLB commissioner Rob Manfred if he was able to get reinstated in 2015 but to no success.
In 2017, Joey Barton was banned for 18 months after the FA announced that he had placed approximately 1,260 bets on matches, including some he was involved in. On top of that, he was fined 30,000 GBP.
Playing with Burnley at the time, Barton was found to have been betting between 2006 and 2016. The FA released a list of 30 bets that were the “most pertinent”, of which two he was playing in. He also placed a bet on the 2011 FA Cup, a match which he was playing in.
“I was not involved in the match day squad for any of those games,” he wrote in defense of betting on his own matches. “I had no more ability to influence the outcome than had I been betting on darts, snooker, or a cricket match in the West Indies".
Despite contesting the ban and hoping to shorten it, the ban sent him into an early retirement.
