The NFL Players Association stated Wednesday that it had sent a formal request for information to the league regarding Washington’s practice facility being searched last week by federal authorities.

Ryan Vermillion, the head athletic trainer, was placed on administrative leave due to what a Washington spokesperson called an ongoing criminal investigation that had nothing to do with the team.

Two people with knowledge of the matter said to The Associated Press federal law enforcement officers, including agents from U.S. Drug Enforcement Administration served a search warrant at this facility last week. According to one person, another search warrant was issued at a local residence.

According to the NFLPA, this situation “directly affects player safety and health.” The NFLPA demanded that language be included in our collective bargaining agreement which obligates clubs and states to comply with all federal and state laws and regulations. We are eager to learn more about how we can protect our players.

A spokesperson for the league declined to comment.

Washington practiced Wednesday without Vermillion who was not able to travel with the team for Atlanta’s game last week. Bubba Tyer (former trainer), was present at the practice facility as well as on the field during practice.

When asked Monday about Vermillion by coach Ron Rivera, who has been working with him for over a decade and was formerly with Carolina, Ron repeatedly referred back to the team statement.

Rivera stated, “I’m not going comment on how I feel about it.” Rivera said, “That would be beyond what I need.”
