The NFL Players Association has charged that the teams are colluding to avoid giving players guaranteed contracts.
The union filed the complaint last month, two people with knowledge of the situation told The Associated Press on Tuesday.
The people spoke on condition of anonymity because it is a legal dispute.
NFL general counsel Jeff Pash sent a memo Oct. 20 informing teams of the union’s indictment, one of the people said.
A league spokesman declined to comment. The NFLPA did not immediately respond to a request for comment.
The union charges that team owners and executives agreed not to offer guaranteed contracts after the Cleveland Browns signed Deshaun Watson to a five-year, $230 million guaranteed deal in March.
No player has received a guaranteed deal since Watson. Kyler Murray and Russell Wilson signed lucrative contracts after Watson. Lamar Jackson couldn’t agree to anything with Baltimore because he wanted a fully guaranteed contract. Ravens owner Steve Bisciotti criticized Watson’s contract and other owners raised concerns about it.
The NFLPA is not seeking to terminate the collective bargaining agreement in this dispute.
