Parkes/MacDonald Prods. has acquired movie and TV rights to the book “League of Denial: The NFL, Concussions and the Battle for Truth.”

The deal comes less than four months after the NFL reached a $765 million settlement with more than 4,500 former players for concussion-related compensation, exams and medical research.

The book, written by ESPN reporters and brothers Mark Fainaru-Wada and Steve Fainaru, centers on the dangers of football-related head injuries and the NFL’s failure to protect its players. The book served as the basis of a PBS “Frontline” documentary that aired after ESPN pulled out of what had been a joint investigation with PBS.

The tome centers on Pittsburgh Steelers player Mike Webster, who played 16 seasons starting in 1974 and died in 2002 at age 50, and the pathologist who examined Webster’s brain.

“League of Denial” will be produced by Walter Parkes and Laurie MacDonald under the Parkes+MacDonald/Image Nation banner. The partnership’s documentary “I Am Malala” began shooting in July with Davis Guggenheim directing.

Joe Veltre of Gersh represents the authors of the book.

News of the deal was first reported by Deadline Hollywood.
