Jonesboro Police Chief Franklin Allen says the 46-year-old Blaylock is also charged with driving on a suspended license and failure to maintain his lane in the Friday crash.
Police say Blaylock was driving an SUV that crossed the center line and struck a van. A van passenger, 43-year-old Monica Murphy, died hours later. Her husband survived.
Atlanta Medical Center spokeswoman Nicole Gustin said Blaylock was in fair condition Monday. He initially was on life support.
Allen says police are working to determine the cause and that alcohol doesn't appear to be a factor. Blaylock told investigators he blacked out just before the wreck. It's unclear if he has an attorney.
Blaylock played 13 NBA seasons, with New Jersey, Atlanta and Golden State.
