"He's very glad to be back home," said his agent, Doug Rogalski, in an e-mail Friday afternoon.
The 20-year-old Sapp had been hospitalized since Dec. 11, when he was taken to an Orlando-area emergency room following an apparent seizure after completing his early afternoon workout.
Sapp was diagnosed with viral meningitis and chronic sinus disease. Doctors determined that the sinus condition led to an abnormal susceptibility to the meningitis virus.
Sapp's course of treatment included heavy doses of antibiotics to treat the meningitis and pneumonia, and included a surgical procedure to rectify his sinus issues on Dec. 14.
Sapp required the use of a respirator for more than two weeks after suffering three episodes where he stopped breathing.
