American Football Rules - Free Kick Downs - Kickoffs

Kickoffs

A kickoff is a type of free kick where the ball is placed on a tee (or held) at the kicking team's 30-yard line (40 for high school). In the 2011 NFL Season, changes were made regarding kickoffs to limit injuries. Kickoffs were returned from the 30-yard line to the 35-yard line, repealing a 1994 rule change. In addition, players on the kickoff coverage team cannot line up more than 5 yards behind the kickoff line, minimizing running starts and thus reducing the speed of collisions. The kicking team's players may not cross this line until the ball is kicked; members of the non-kicking (or "receiving") team are similarly restrained behind a line 10 yards further downfield (the 40-yard line, or 50 for high school). A valid kickoff must travel at least this 10-yard distance to the receiving team's restraining line, after which any player of either team may catch or pick up the ball and try to advance it (a member of the kicking team may only recover a kickoff and may not advance it) before being downed (see "Downed player," below). In most cases, the ball is kicked as far as possible (typically 40 to 70 yards), after which a player of the receiving team is usually able to secure possession (since the members of the kicking team cannot start downfield until after the ball is kicked). Occasionally, for tactical reasons, the kicking team may instead choose to attempt an onside kick, in which the kicker tries to kick the ball along the ground just over the required 10-yard distance in such a manner that one of his own teammates can recover the ball for the kicking side. If it is touched before ten yards, the ball is dead and a re-kick or spot of the ball will be rewarded to the receiving team.
