The NFL issued a new memo to teams laying out rules for offseason programs, according to ESPN.
The league, which made parts of the program voluntary under the collective bargaining agreement, is imposing the rules after failing to reach an agreement with the NFLPA on several issues.
The NFLPA has pushed for an all-virtual offseason due to the ongoing coronavirus pandemic. The players' union also hopes to send a message to the league that players will stop agreeing to contracts that incorporate bonuses for participating in voluntary offseason workouts.
Currently, more than 200 players have workouts bonuses requiring them to attend offseason workouts to receive their bonuses.
