Their suit, filed yesterday in a U.S. district court in Missouri, alleges that the NFLPA "withheld information from the players about the risks of head injuries." It names former presidents Trace Armstrong, Troy Vincent, and Kewin Mawae.In a statement, the NFLPA responded that the suit "erroneously alleges that the NFLPA knowingly and fraudulently concealed from players the risks of head injuries players faced by playing in NFL games and practices over the last several decades.
