A quarterback can complete a pass, a receiver can make a spectacular catch, and a flag can still change everything. Keeping track of who spotted the foul, where the ball should go next, and whether the play clock is running takes a coordinated crew—not one person watching the whole field.
American football officials share that work. Each has a defined area to watch, but their calls often depend on communicating with one another and applying the rules together.
How many officials are on the field?
An NFL game uses seven on-field officials. Most major college games use eight, adding a center judge; crew sizes can vary at other levels. High school games may use five, six, or seven officials, depending on the competition and available crew.
There may also be an off-field replay official and other video-review staff, depending on the league. They assist with review procedures, but they are separate from the officials working on the field.
The seven standard positions are the referee, umpire, down judge, line judge, field judge, side judge, and back judge. The exact positioning and division of duties can vary by league, but the shared aim is the same: cover the players, boundaries, timing, and action around the ball.
What each official does
| Official | Main focus |
|---|---|
| Referee | Overall crew leader, quarterback area, penalty announcements |
| Umpire | Interior line play, blockers, and contact near the snap |
| Down judge | Line of scrimmage, line to gain, and chain crew |
| Line judge | Line of scrimmage and sideline action on the opposite side |
| Field judge | Deep coverage, catches, and boundary plays |
| Side judge | Deep coverage from the other side and sideline plays |
| Back judge | Deep middle of the field and play-clock duties in many leagues |
Referee
The referee leads the crew and is often recognizable by the white cap. Before the snap, the referee checks that the game can proceed; during the play, the referee watches key action around the quarterback and the backfield. After a foul, the referee reports the ruling, explains the penalty, and indicates its enforcement to players and spectators.
That does not mean the referee makes every call alone. A flag from another official may prompt a crew discussion, especially if the foul’s location or enforcement needs clarifying. The referee then gives the crew’s decision.
Umpire
The umpire focuses on the crowded area around the line of scrimmage. That means watching blockers and defenders for actions such as holding, illegal contact, or a false start. The umpire also helps check player equipment and makes sure the ball is ready for play under the crew’s mechanics.
Interior line play is difficult to judge from the stands: a legal block and a hold can look similar when bodies are moving quickly. The umpire’s angle and close attention to the point of contact help the crew make that distinction.
Down judge and line judge
The down judge works along one sideline near the line of scrimmage. This official tracks the ball’s position, watches for infractions such as offsides, and usually coordinates with the chain crew—the people operating the sideline markers that show the down and line to gain. The down judge helps confirm whether the offense has earned a first down.
The line judge works near the line of scrimmage on the opposite side. This official has similar responsibilities there, including watching the neutral zone and nearby sideline action. Together, the two officials help judge whether a runner or receiver is in bounds and where the play ends.
Field judge, side judge, and back judge
These three officials cover deeper parts of the field, where passes and boundary decisions often demand a clear view. The field judge and side judge work on opposite sides, watching receivers and defenders for actions such as pass interference, as well as whether a catch is completed near the sideline.
The back judge generally works deep in the middle of the field. This official helps cover long passes and plays near the goal line. In many leagues, the back judge also monitors the play clock, including the time allowed before the snap. The deep officials share responsibility on many plays; no single one can see every angle of a contested catch.
How officials work as a crew
Before the snap, officials take positions that give them different views of the formation. Once the play begins, each watches a particular area rather than following the ball alone. For example, on a pass downfield, one official may focus on the receiver’s feet at the sideline while another watches the defender’s contact. This helps the crew judge both the catch and any potential foul.
Officials communicate with hand signals, brief discussions, and, when needed, their microphones. A flag identifies a possible foul, but the crew still has to determine what happened, whether the action broke a rule, and how the penalty applies. Some penalties stop play immediately; others are called after the play has ended. The referee announces the result, including options for the non-offending team when the rules allow them.
Clock management is also shared work. Officials track game time and the play clock according to their league’s mechanics, and they signal when a clock should stop or restart. On a close first-down measurement, the crew checks the ball against the line to gain; the chains provide a visible reference, though the spot of the ball remains an officiating judgment.
Replay and differences between leagues
Replay rules vary by competition. In leagues with video review, an off-field official or review system may help assess eligible plays. Reviews do not replace the on-field crew’s job, and not every judgment call can necessarily be reviewed. The referee communicates the final ruling on the field after the review process is complete.
Rules and crew mechanics are not identical at every level. NFL and college football differ in some procedures, while high school games follow rules set by their governing bodies. That is why a clock procedure, review option, or official’s precise assignment may not be exactly the same from one game to another.

Frequently Asked Questions
Who makes the final decision on a penalty?
The crew determines what happened and how the rules apply. The referee announces the crew’s ruling and explains the penalty and its enforcement.
Why are there several officials watching the same play?
They cover different areas and angles. One official may watch the ball’s location while another monitors contact between a receiver and defender, making it less likely that important action goes unseen.
Does every flag mean the team will be penalized?
No. A flag signals a possible foul. Officials may confer and decide that no foul occurred, or the team that did not commit the foul may have a choice under the rules.
How many officials work an NFL game?
There are seven on-field officials in a standard NFL crew: a referee, umpire, down judge, line judge, field judge, side judge, and back judge. Replay personnel work off the field.

Football officiating is a team effort built around clear assignments and constant communication. Knowing the officials’ positions helps you follow close calls, understand how a first down is measured, and see why the person nearest the ball may not be the only one involved in a ruling.
