Play question?

[Snake~eyes]

That's funny, I was just talking to Grant about this play because it happened in one of my games. Here is a caseplay that covers it:

8.5.3 SITUATION A: With fourth down and 7 from K's 10, K1 punts from the end zone. The kick is partially blocked and is just barely moving at K's 2-yard line when R1's muff provides a new force which moves the ball into, and out of, the end zone. RULING: Touchback. Because it was the new force by R1 which caused the ball to go out of K's end zone, the result is a touchback instead of a safety. (2-13-1;8-5-3b)
