The pull may occur only after an official has signaled readiness for the receiving team.
Players on the pulling team may move about their end of the field anywhere behind their brick mark prior to the pull, but no foot may be on or across the horizontal line extending from the brick mark when the pull is released.
Players on the receiving team must have at least one foot on their goal line, and they may not change their order or substitute after signaling readiness. Players on the receiving team may have their second foot on, in front of, behind, to the side of, or above their goal line.
All players must be fully visible to the opposing team from the time between signaling readiness and the pull.
