The head linesman is the official on the sideline that straddles the line of scrimmage looking for scrimmage violations like offsides or encroachment and penalties like illegal motion, illegal shifts , illegal use of hands and illegal men downfield.
The head linesman rules on all out-of-bounds plays along the sideline where positioned. The head linesman keeps tabs on the chain crew and marks the chain to a yard marker on the field as a reference point for a measurement on the field. Also, the head linesman keeps track of all eligible receivers and marks the forward progress of the ball.
The following is a collection of resources for training as a Head Linesman. These are provided as general training tools for new officials or officials who are trying to expand their training.
