Players at the league’s annual owners meetings are facing discipline after allegedly throwing objects from the stands during the games.
More than 1,500 players took part in the meetings in Las Vegas.
A number of the players were arrested in a domestic dispute, which led to the arrest of their teammates.
Several players were charged with misdemeanors, including assault and battery on a police officer, which carry a maximum sentence of three years in prison and a fine of $1,000.
The players have been given until January 21 to turn themselves in to authorities.
NFL Players Association spokesman Eric Winston said the NFLPA would work with authorities to make the players accountable.
“The league has not received any official statement from the NFL regarding any player’s conduct, and the NFL does not comment on ongoing investigations,” he said.
“The NFLPA has also reached out to the players’ lawyers to discuss any potential legal action that may be appropriate, and we will work with them to determine the best course of action.”NFL spokesman Joe Lockhart said the players involved were disciplined in the “most professional and responsible manner possible”.
“The players’ actions were not in accordance with the values of our game,” he added.
