Rule 7 – Section 3 – Article 7 – Incomplete Pass
a. Any forward pass is incomplete if the ball is out of bounds by rule (Rule 4-2-3) or if it touches the ground when not firmly controlled by a player. It also is incomplete when a player leaves his feet and receives the pass but first lands on or outside a boundary line, unless his progress has been stopped in the field of play or end zone (Rule 4-1-3-p). (A.R. 2-4-3:III) (A.R. 7-3-7:I)
b. When a legal forward pass is incomplete, the ball belongs to the passing team at the previous spot.
c. When an illegal forward pass is incomplete, the ball belongs to the passing team at the spot of the pass (Exception: If Team B declines the penalty for an illegal pass thrown from the end zone, the ball shall next be put in play at the previous spot.) (A.R. 7-3-7:II- III)
