CBS has filed a federal lawsuit in Minneapolis to clarify who can use the statistics that underlie fantasy football leagues.

The lawsuit filed earlier this week claims the NFL Players Association has threatened to sue the company if it does not pay licensing fees for the statistics.

CBS Interactive seeks a ruling saying that the players cannot control use of the publicly available numbers and cannot demand that CBS pays for their use.

Players association attorney Jeffrey Kessler isn't commenting because he just got the lawsuit.

In a case involving a Missouri-based company's fantasy baseball games, Major League Baseball players argued they should be paid for the commercial use of their names. The 8th U.S. Circuit Court of Appeals in St. Louis ruled against the players earlier this year.
