NFL chief disciplinary officer B. Todd Jones said Wednesday the league's ability to obtain details about alleged off-field misconduct by its players is "limited."
Ian Rapoport of the NFL Network provided comments from Jones about the NFL's investigative power.
"There is information we can't get when we need it," he said. "But when we get it, we act on it."
The remarks come two weeks after the league received criticism for failing to obtain security video of former Kansas City Chiefs running back Kareem Hunt shoving and kicking a woman during a February altercation inside a Cleveland hotel before it was posted by TMZ Sports in late November.
After the footage became public, the NFL announced Hunt was being placed on the Commissioner Exempt list, preventing him from practicing or playing in games, while the league further investigated the situation, including a "review of the new information that was made public today."
The Chiefs released Hunt later the same day, stating he was "not truthful" in discussions with team management about the incident.
A source told TMZ Sports the NFL made "multiple attempts to obtain the video," but was turned away by both the hotel and the Cleveland Division of Police.
Courtney Astolfi of Cleveland.com reported Feb. 12 two conflicting police reports were filed following the incident. One listed Hunt as the suspect and the other named Abigail Ottinger, the 19-year-old woman seen in the video, as the suspect with both sides alleging assault.
No criminal charges were filed in the case.
Mark Maske of the Washington Post reported Tuesday the league has no immediate plans to change its process for off-field investigations despite the critiques for its handling of situations involving Hunt, Washington Redskins linebacker Reuben Foster and former Baltimore Ravens running back Ray Rice.
The NFL has yet to announce any additional discipline for Hunt, who remains a free agent.
