More than half of all NFL players who were suspended in 2014 were suspended for a violation of the league’s rules regarding player conduct.
The NFLPA released its report Thursday, and the union said it found that in the three years leading up to the start of the 2015 season, more than 1,200 players were disciplined for violations of the NFL’s substance abuse policy.
The union said in its report that about 1,300 of the suspended players violated the policy.
The report also said the league has failed to enforce the substance abuse policies in its stadiums, and it says the league is failing to address the issue of players who may be suspended or disciplined based on performance-enhancing drugs.
The report said the NFL has made more than 2,500 discipline referrals to the league office and that the league “has made no effort to address these issues.”
The union also criticized the league for not addressing players who have tested positive for performance-related drugs.
It said the union received information from multiple sources in the past year that several players tested positive in the previous two seasons.
That information is being shared with league officials, but the union’s report said there was no communication to the players.
The union’s investigation found that the NFLPA’s findings of misconduct have not been independently verified by other independent groups or independent laboratories.
The unions report said it “has received conflicting information from independent laboratory tests, including results from the NFL Players Association.”
The league did not immediately respond to a request for comment.
