Oral arguments are scheduled April 9 in U.S. District Court on the motions.

More than 3,500 former players have sued the NFL, alleging that not enough was done to inform them about the dangers of concussions and not enough is being done today to take care of them.

The league calls the cases a labor issue that should be governed by collective bargaining agreements, not the legal system.

The players say those agreements didn't address long-term brain injuries and the league has a common-law duty to protect players. They also allege that the NFL committed fraud by concealing risks of repeated head trauma.
