One day after rejecting the latest offer from owners, NBA players filed antitrust lawsuits against the league in two courts Tuesday.

The suit filed in Minneapolis lists NBA players Caron Butler, Ben Gordon, Anthony Tolliver and would-be rookie Derrick Williams as plaintiffs.

In the Northern District of California, another suit featured reigning NBA scoring champion Kevin Durant among its plaintiffs.

The players union broke up on Monday, opening the door for litigation against the NBA much like what happened in the earliest days of the NFL lockout.

The NBA's lockout is more than four months old. The season was supposed to start November 1.
