WASHINGTON (AP) - The NFL confirms it has locked out the players - the sport's first work stoppage since 1987.
In a statement Saturday morning, the league said it was calling on the union to return to negotiations immediately. The Associated Press reported overnight the NFL imposed a lockout at midnight.
On Friday, negotiations between the sides broke off hours before their collective bargaining agreement expired. The union decertified and 10 players, including Tom Brady and Peyton Manning, sued the owners in federal court.
A lockout is a right management has to shut down a business when a CBA expires. There can be no communication between teams and current NFL players; no players can be signed; teams won't pay for players' health insurance.
