(CBS SF) – NFL owners have passed a player safety rule barring ball carriers from using the crown of their helmets to make contact with a defender in the open field.

The owners have also voted to eliminate the tuck rule, which was one of the most criticized rules in pro football. Now, if a quarterback loses control of the ball before he has fully protected it after opting not to throw, it is a fumble.

“You can’t fight it, you have to coach it,” Coach Madden told the KCBS morning crew. “If you look at it, I don’t think anyone ever at any level wanted to have a guy hit with the crown of his head with the top of his head. That’s where you have your head down to hit and all the pressure not only goes to your head but to your neck. And I don’t know that anyone in the history of football ever taught anyone to do that or told anyone to do that.”
