What is holding panelty in NFL?

Holding penalty in the NFL occurs when a player illegally grabs or holds an opponent or a teammate, impeding their movement during a play. It is most commonly called on offensive players, particularly offensive linemen, who hold defensive players to prevent them from reaching the quarterback or ball carrier. The penalty typically results in a loss of 10 yards from the previous spot. Defensive holding can also be called, usually resulting in a 5-yard penalty and an automatic first down for the offense.
