NFL.com cites an NFL Films statement Friday about the 68-year-old Sabol, who was hospitalized March 5 in Kansas City, Mo., after suffering a seizure.
"(Sabol) will begin treatments soon," the company's statement said. "Steve is in good spirits and is deeply appreciative of everyone's good wishes."
Sabol has worked with NFL Films since 1964. His father, Ed, was elected on the day before the Super Bowl last month to the Pro Football Hall of Fame in Canton, Ohio.
