Five months earlier, in November 2007, Reggie retired from Disney, to devote himself to rehabbing his knee and saving his leg. Eighteen months after that, Disney stopped insuring him. That was mid-2009. Reggie bought his own health insurance. It does not cover pre-exisiting conditions. His rehab is at his own expense.
