NEW YORK (AP) — The head of the NFL players association says the union wants to hold the league and its teams accountable for confidential information about draft prospects being leaked.

Combine drug test results and medical information about players have been reported by various media outlets leading up to the draft, which starts Thursday night in New York.

Incoming players are not represented by the union until they are drafted. Still, NFLPA executive director DeMaurice Smith says the union is concerned the league is not properly treating its future members.

Smith told a small gathering of reporters on Wednesday: “We are reviewing the potential actions that the union can take on behalf of those players.”

He says the union is looking into “civil, regulatory and potentially CBA remedies that we could pursue.”
