Details of his lavish 30th birthday party also resurfaced. Peterson reportedly bought first-class plane tickets to Houston for a guestlist of 320 family and friends.
The Arabian-themed affair included snake charmers from Dallas, world-renowned belly dancers from New York, Jamie Foxx as DJ and a rented lemur.
Peterson entered atop a camel and spent the night seated on a throne with a python draped around his shoulders.
Peterson's lawyer, Chase Carlson, issued a statement this week revealing the ex-Minnesota Vikings star is in financial straits after trusting the wrong people.
"The truth behind Adrian Peterson's current financial situation is more than is being reported at this time," the statement read. "Because of ongoing legal matters, I am unable to go into detail, but I will say this is yet another situation of an athlete trusting the wrong people and being taken advantage of by those he trusted. Adrian and his family look forward to sharing further details when appropriate."
Peterson is currently facing three lawsuits, two of which were filed within the past eight weeks. The first suit was filed in 2017 by a Minneapolis bank, which accused Peterson of defaulting on a $2.4 million loan he took out in 2016, according to ESPN. Last year, he was ordered to pay back more than $600,000.
Peterson also took out a separate $4 million loan just a month before, according to court records obtained by the Baltimore Business Journal. He later missed his first payment on the loan.
A third lawsuit filed by a lender in Pennsylvania claims Peterson defaulted on a $5.2 million loan, which he reportedly took out to try and pay off his previous debts.
Billy Corben, who produced and directed Broke — the ESPN 30 for 30 documentary which examined how athletes blew their wealth — told WCCO radio "as surreal as it sounds, it is so easy to do".
"Oftentimes, players come from very humble beginnings and suddenly, almost overnight, are multi-millionaires. And when you don't have the experience of preserving wealth and growing wealth, it's a very onerous and complicated process," he said.
"When you are competitive people, which athletes are by their very nature and profession, you will get into competitive spending and will want the fanciest car and the best suits (compared with) your fellow players in the locker room.
"And of course, as, as we're seeing, allegedly in the Peterson case, the individuals that athletes often trust with the responsibility of preserving and growing their wealth, can't be trusted."
