Former Redskins and Broncos star Clinton Portis and 13 other ex-NFL players have been charged or will be charged with defrauding the NFL's medical plan for retired players.
The Feds say Portis -- who is facing up to 20 years -- helped to concoct a scheme in which ex-players filed fake insurance claims and submitted them to the league for reimbursement.
Officials say some of the fraudulent claims included the players looking to be reimbursed for things like pricey hyperbaric oxygen chambers, ultrasound machines and electromagnetic therapy devices designed for use on horses.
Officials say the plan paid out more than $3 MILLION to the former NFL players ... before their scheme was eventually snuffed out by investigators.
The other former players involved are Correll Buckhalter, Carlos Rogers, Joe Horn, Reche Caldwell, Robert McCune, John Eubanks, Tamarick Vanover, Ceandris Brown, James Butler, Fredrick Bennett, and Etric Pruitt.
