Football Encroachment Penalty

The encroachment penalty in football is when a defensive player moves across the line of scrimmage and contacts an offensive player prior when the ball is snapped. This penalty results in the offense gaining five yards.
Although similar, this penalty is different from an offside penalty on the defense, which is called when a defensive player moves across the line of scrimmage before the ball is snapped, because an encroachment penalty includes contact between two players.
Definition
The encroachment penalty is called when a defensive player crosses the line of scrimmage and makes contact with an offensive player before the snap. An encroachment penalty can also be called if a defensive player makes contact with the ball before it is snapped. The encroachment penalty is always called as a dead ball penalty. This means that the referees will blow their whistle and prevent a play from happening. It is similar to other penalties like false start and neutral zone infraction in this way.
An encroachment penalty is a pre-snap penalty that is very similar to many other pre-snap penalties on the defensive team. The difference between an encroachment penalty compared to an offside penalty or a neutral zone infraction penalty is that an encroachment penalty means the defensive player must make contact with an offensive player.
An encroachment penalty will not be called if the offensive player is the first person to move. Encroachment has always been a penalty because of the unfair advantage that it would give to the defense if this type of penalty were not called.
Encroachment penalties are generally very easy for officials to call because it is obvious when the defensive player comes into contact with the offensive player. However, it can be difficult if an offensive player moves at almost the same time as the defensive player goes offside. Encroachment is widely seen as an obvious penalty to notice.
