Encroachment is when a defensive player makes contact with an offensive player before the snap of the ball.
A dead ball foul is a term in which the ball has not been inbounded, the clock is stopped, thus a "dead ball," and a foul has been commited.
Yes. Play is stopped the moment the defender crosses into the neutral zone. Technically, this is called "encroachment." There is no "offsides" foul in high school football.
No, a foul ball is a dead ball, so nobody advances.
after the batter hits the ball and it's a fair ball it's not a dead ball. if the ball lands in foul territory, it's a foul ball.
dead ball.. no out.
If the ball is in fair territory, the fact that the fielder is standing in foul territory does NOT make the ball foul. the same as if a ball is foul, the fielder standing in fair territory doesn't make the ball fair.
