PHILADELPHIA (AP) — Lawyers for former NFL players plan to file a single lawsuit Thursday consolidating scores of complaints brought against the league in the past year accusing the NFL of concealing information linking football-related head injuries to permanent neurological problems.

Plaintiffs lawyers say more than 80 pending lawsuits are consolidated in the “master complaint” being filed in Philadelphia. They involve thousands of retired players.

A federal judicial panel has consolidated the cases before U.S. District Judge Anita Brody. The lawsuits aim to hold the NFL responsible for medical monitoring and treatment of the veteran players.
