 The NFL says it will stop settling concussion lawsuits using a race-based formula that assumes black players have a lower level of cognitive function. America's top flight football league also pledged to review previous brain injury claims that have been settled via the practice known as race norming. Two black players filed a civil rights lawsuit over the practice. One black player involved in the litigation called the policy classic systemic racism. More than 2,000 former NFL players have lodged dementia claims but fewer than 600 have received compensation.
