The NFL and the lead attorney for about 20,000 former players on Wednesday both promised to end “race-norming” — a controversial practice that curves Black players’ cognitive test scores with data that assumes a lower level of function — as part of the payout process in the $1 billion-plus settlement of class-action concussion litigation against the league.

The statements from the NFL and attorney Chris Seeger came as the practice of race-norming in the settlement payout process, first brought to public attention last year in a lawsuit by two former players, has drawn heightened scrutiny in the courts and media.

“We are committed to eliminating race-based norms in the program and more broadly in the neuropsychological community,” the NFL said in a statement.
