This is a Splint Screen of sorts, because House Republicans are debating the fate of one of their highest ranninging members, liz cheney, after backlash of her vote to impeach president trump.

Were going to turn next here this evening to an abc news investigation. Two former nfl players speaking for the first time on camera about their time in the league, saying they experienced concussions and now suffer from depegs, memory loss and bouts of anger. Two players suing the league, claiming the nfl uses a formula that assumes black players start at a lower cognitive level than white players, making it harder for black former players to qualify for compensation. Tonight, how the league is now responding. And heres abcs ryan smith. Look out. Down he goes reporter kevin henry played eight seasons in the nfl. Thats a good, clean hit. Reporter tonight, he is accusing the league of what he says is a doublestandard when it comes to race and the concussion settlement. Im banged up. Im beat up and the part that you dont see is up here. You dont see how my brain is beat up. They dont hit me less or reporter kevin henry and another former player, najeh davenport, are suing the nfl, accusing them of avoiding paying headinjury claims based on a formula that discriminates on the basis of race. The formula, they say, assumes black players start at a lower cognitive level than white players, making it harder for black former players to qualify for compensation. Its a controversial practice called race norming, in which test results are adjusted to account for supposed differences between demographic groups. Theres the assumption that people of different races, especially black people, that their bodies function differently. Reporter and while the nfl insists the formula is optional, an abc news investigation has found that some clinicians who evaluate former nfl players believe they are required to apply the formula. Football doesnt give you an expiration date, it just happens. You just expire. Ive had ten concussions or more and thats not even counting practice. Reporter after his time in the league, kevin henry says he began suffering from depression, memory loss and bouts of anger. In 2017, he underwent a series of tests. A doctor determining that henry was suffering from a cognitive decline consistent with mild dementia. So he submitted a claim to the landmark 2013 nfl Concussion Settlement Program rr He Cims Su Reled Validity of the tests and asserted that the evaluation used inappropriate norms.

And the Concussion Settlement Program was agreed to by all parties with the assistance of Expert Neuropsychological Clinicians and it relies on widely accepted and longestablished testing and scoring methods. Now 52 years old is it gone . Yeah. Reporter kevin henry says daily life is a constant struggle. It takes everything in me to keep from crying, man. I just want to be i just want to be looked at the same way as a white guy. So, lets bring in ryan smith tonight. And ryan, where does this lawsuit stand tonight . The case still being litigated . Reporter yes, david. The players onhe nfls motion to dismiss the case. David, as of now, the nfls received 3,000 claims for compensation and paid out about 1,200 of them to former players and their families, toe tachling 800 million.
