During the last several months, former NBA forward Antoine Walker has been pursued by multiple financial institutions for unpaid debts.

According to the Boston Globe, those debts total more than $4 million.

Walker earned more than $110 million during his career, but a number of NBA sources claim that the former Celtic squandered away all of his money.

"I know Antoine has enjoyed himself," said a former teammate. "He had a good time, as all professionals who are in that situation should. But there's tough lessons you learn about the responsibilities that come with being a professional athlete that makes a lot of money. Sometimes this is one of the consequences to that."
