Per a league source, the NFL plans to proceed, as well.
Specifically, the league will schedule interviews with all relevant parties, and the NFL will cooperate with the NFLPA.
If any breach of confidentiality under the substance-abuse program can be substantiated, the league will discipline all responsible parties. The league also expects the union to take action, in the event that the investigation determines someone from the NFLPA or the player’s side was involved in the leaking of information.
That last part hints at speculation from some that Freeman’s camp may have leaked information regarding the player in order to justify efforts to pressure the Bucs to release Freeman, by creating the impression the team was making the leaks.
It nevertheless will be difficult for the NFL or the NFLPA to piece prove who did and didn’t talk, given that the media likely won’t be cooperating — and neither the NFL nor the NFLPA has the ability to compel cooperation.
