RULE NO. 8—OUT-OF-BOUNDS AND THROW-IN
Section II—Ball
a. The ball is out-of-bounds when it touches a player who is out-of-bounds or any other person, the floor, or any object on, above or outside of a boundary or the supports or back of the backboard.
b. Any ball that rebounds or passes behind the backboard, in either direction, from any point is considered out-of-bounds.
c. The ball is caused to go out-of-bounds by the last player to touch it before it goes out, provided it is out-of-bounds because of touching something other than a player. If the ball is out-of-bounds because of touching a player who is on or outside a boundary, such player caused it to go out.
d. If the ball goes out-of-bounds and was last touched simultaneously by two opponents, both of whom are inbounds or out-of-bounds, or if the official is in doubt as to who last touched the ball, or if the officials disagree, play shall be resumed by a jump ball between the two involved players in the nearest restraining circle.
e. After the ball is out-of-bounds, the team shall designate a player to make the throw-in. He shall make the throw-in at the spot out-of-bounds nearest where the ball crossed the boundary. The designated thrower-in or his substitute shall not be changed except following a regular or 20-second timeout.
f. After any playing floor violation, the ball is to be put into play on the sideline.
g. If the ball is interfered with by an opponent seated on the bench or standing on the sideline (Rule 12A—Section III—c), it shall be awarded to the offended team out-of-bounds at the free throw line extended.
