The NFL has abruptly dropped its plan to challenge approved dementia diagnoses in a concussion case.

Lawyers from the players are accusing the NFL of trying to delay payments and rewrite the $1 billion settlement.

The NFL had asked to challenge some diagnoses made by settlement-approved doctors and upheld by a court-appointed administrator whose decisions are supposed to be final. 

The NFL argued that it had agreed to remove a $765 million cap on payouts only in exchange for “a clear demarcation of the boundary between compensable and non-compensable levels of impairment.”
