One of the most familiar faces on the NFL Network, the president of NFL Films, Steve Sabol, is about to begin chemotherapy and radiation treatment for a brain tumor, reports NFL.com.

Sabol, 68, had a seizure two weeks ago in Kansas City and was subsequently diagnosed with a mass on the left side of his brain.

Sabol, winner of 27 Emmys for his work with NFL Films, has been actively involved as a commentator in the NFL Network programs that make extensive use of the league’s vast film library. Steve’s father, Ed Sabol, who founded the company, was named to the 2011 Hall of Fame class just last month.
