A year after the process for compensating former NFL players under the $1 billion concussion settlement agreement officially began, calls that the administrative process is too slow and clandestine have begun to mount.

On Monday, co-lead class counsel filed a motion seeking to have U.S. District Judge Anita Brody of the Eastern District of Pennsylvania conduct a hearing regarding possibly intervening into the claims process. By late Tuesday, a law firm representing more than 240 retired players joined the motion, saying some claims have been “unreasonably and inexcusably delayed,” and another attorney filed a motion saying “the settlement is failing to provide a fraction of what the NFL promised.”
