The NFL Players Association (NFLPA) has officially announced that the use of sleep monitor devices outside of games and practices is in violation of the Collective Bargaining Agreement (CBA). The CBA does allow the league to require players to wear sensors and other tracking devices during games and practices to collect performance, medical and safety-related information. However, NFLPA executive director, DeMaurice Smith, is seeking an order to immediately discontinue the use of these unapproved sensor devices until such use is approved by the NFLPA.
Teams like the Eagles and Seahawks believe that sleep-monitoring devices play a vital role in the performances of the players.
