where do you punt from after a safety
Safety (gridiron football score) After a safety is scored, the ball is put into play by a free kick. The team that was scored upon must kick the ball from their own 20-yard line and can punt, drop kick, or place kick the ball. In professional play, a kicking tee cannot be used – however, a tee can be used in high school or college football. Once the ball has been kicked, it can be caught and advanced by any member of the receiving team, and it can be recovered by the kicking team if the ball travels at least 10 yards and bounces at least once or a player of the receiving team touches the ball.[8][9]
Pass interference In the NFL and the Canadian Football League the penalty for defensive pass interference is an automatic first down at the spot of the foul. If the foul occurs in the end zone, the ball will be placed at the one-yard line (or half the distance to the goal if the line of scrimmage was already inside the 1 yard line). In U.S. college football and amateur Canadian football, the penalty is to the spot of the foul, up to a maximum of 15 yards from the previous spot, and an automatic first down. In U.S. high school rules the penalty is 15 yards from the previous spot with the down replayed for both offensive and defensive pass interference. Prior to 2013, the penalty for defensive pass interference also included an automatic first down while the penalty for offensive pass interference included a loss of down. In the NFL and CFL, the penalty for an offensive pass interference is 10 yards from the previous spot. In amateur Canadian football, the penalty is 15 yards.
