Rule 6 – Section 5 – Article 1 – Dead Where Caught
b. If a Team B player makes a valid fair catch signal, the unimpeded opportunity to catch a free or scrimmage kick continues if this player muffs the kick and still has an opportunity to complete the catch. If he (or another Team B player) subsequently catches the kick, the ball is placed where he first touched it. This protection terminates when the kick touches the ground. (A.R. 6-5-1:I-II)
