4-2-2a Exception A holder with his knee(s) on the ground who has a teammate in position to kick at the snap as in PlayPicA, is allowed to rise to catch or recover an errant snap. The ball remains live if he goes to his knee(s) immediately after catching or recovering the snap. The holder is then allowed in PlayPic C or PlayPic D to do what he could have done if the snap had been accurate and he had not risen from his knee(s) to begin with. If the snap is muffed or the holder fumbles, he may recover with his knee(s) on the ground and place the ball for kick or may rise with it.
4-2-2a Exception 2 The snap in PlayPic A is errant. The ball remains live if the holder rises and catches or recovers an errant snap and immediately returns his knee(s) to the ground (PlayPic B) and places the ball for a kick or again rises to advance, hand, kick or pass (PlayPic C).
4-2-2 Exception 2 No. 4 is in position to kick and the holder has a knee(s) on the ground at the snap in PlayPic A. The exception to the basic dead ball rule is in effect when both these conditions are being met at the snap. The ball remains live for a kick as in PlayPic B, or if the holder rises with the ball (PlayPic C) to run, pass or dropkick.
4-2-2a Exception, 4.2.2 a-c On a busted play or fake, the holder must rise before advancing, handing or passing as seen in the PlayPic. If the holder rises to catch or recover an errant snap, and immediately returns his knee(s) to the ground and places the ball for a kick or again rises to advance, hand, kick or pass, the ball remains line.
