The National Football League (NFL) made an experimental rule change on March 23, 2016, for the following season stating that two unsportsmanlike conduct penalties on a player would result in an automatic ejection from the game. Some coaches have expressed concern that this could result in a player with one such penalty being goaded by the opposing team into a second penalty to get them removed from the game. From the 2018 season, players who commit flagrant helmet clashes are automatically ejected.
