Former NFL stars Clinton Portis and Joe Horn are among 12 retired players accused of defrauding the league’s retiree health care benefits plan for more than $3 million, according to federal prosecutors.

Ten retired NFL players were charged in two indictments for allegedly submitting phony health care claims seeking to be reimbursed for expensive medical equipment that was never purchased, prosecutors said in a press release . The Department of Justice said it also plans to file charges against two other retired players.

The scheme, which lasted from June 2017 to December 2018, led to over $3.9 million in false and fraudulent claims, of which the plan paid out more than $3.4 million, prosecutors said in a news release.

“Ten former NFL players allegedly committed a brazen, multi-million dollar fraud on a health care plan meant to help their former teammates and other retired players pay legitimate, out-of-pocket medical expenses,” Assistant Attorney General Brian Benczkowski said in a statement.

Four former players were arrested and six agreed to turn themselves in, Benczkowski said.

In addition, the government plans to file criminal information’s charging Joe Horn, the former New Orleans Saints wide receiver, and Donald “Reche” Caldwell, the former San Diego Chargers and New England Patriots wide receiver, with conspiracy, according to the news release.

According to the indictments, the former players submitted phony claims for expensive equipment, including hyperbaric oxygen chambers, ultrasound machines designed for a doctor’s office to conduct women’s health exams, and electromagnetic therapy devices for horses.

The claims were for about $40,000 to $50,000 each, prosecutors said. They relied on fabricated invoices, prescriptions and letters of medical necessity, prosecutors said.

In addition, some defendants recruited other retired players to participate in the scheme in exchange for kickbacks and bribes that ranged from a few thousand dollars to $10,000 or more per claim, prosecutors said.
