Use of Bean Bag
GENERAL BEAN BAG MECHANICS
All officials are to carry at least one bean bag (blue or white) as a part of their uniform equipment. The crew will use the same color bean bag at all levels.
The primary purpose of the bean bag is to mark an important spot during action while the ball is live. There are several critical spots that should be marked by a bean bag:
The spot of first touching of any kick
The spot of the end of a scrimmage kick
The spot of a fumble beyond the line of scrimmage
Forward progress when a play ends out of bounds or an inadvertent whistle.
