Chain Crew - Auxiliary Chain Crew

For professional and college football games, an auxiliary chain crew operates on the opposite side of the field. Here, another "stick" and down indicator box is used so that players and officials can also look at the other side of the field to know where the first down line and the line of scrimmage is, respectively. The auxiliary chain crew also includes the drive start indicator, which is placed at the beginning of a team's drive and stays there until they lose possession. This indicator is only used for statistical purposes to calculate the distance of each drive. It looks similar to a "stick", but it has an arrow (or occasionally a large "X") that points in the direction the offensive team is going.

Members of the chain crew are usually picked by the offices of the home team instead of the league or conference that they play in.
