Play question?

Guys,

almost word for word in the casebook page 89 10.5.5 Sit B.
Both MJT and BktBallRef picked up on it. When I first read it I thought safety too because the kick did not end. But according to the casebook if a "new force" such as a muff is put on the ball now R has put the ball in the EZ and not K! Making it a TB...That is why I wanted to post this...



10.5.5 SITUATION B: K1's scrimmage kick is blocked on K's 5-yard line and is rolling away from the nearer goal line when R1 muffs the ball into K's end zone. K2 recovers the ball and attempts to advance, but is downed in the end zone. During K2's run: (a) R1 holds K3 in the end zone; or (b) K3 holds R1 in the end zone. RULING: In (a), it is a touchback and the basic spot is the 20-yard line. In (b), since the foul is in the end zone, it is a safety.
