Football Referee Positions and Responsibilities
Football officiating crews may consist of three, four, five, six, seven, or more officials depending on the level of competition and the governing organization.
Each official has assigned responsibilities designed to provide coverage of the line of scrimmage, player action, sidelines, passing plays, kicking situations, and game administration.
Referee (R)
The referee serves as the crew chief and generally wears a white cap, distinguishing this position from the other on-field officials.
Common responsibilities include:
-
General supervision and administration of the game.
-
Monitoring the quarterback and assigned backfield action.
-
Ruling on designated passing and quarterback-related situations.
-
Announcing penalties and communicating decisions.
-
Overseeing the pregame coin toss and other assigned administrative duties.
Umpire (U)
The umpire focuses primarily on interior line play, blocking action, and other assigned responsibilities.
Common duties include observing illegal blocks, holding, player safety, and action around the line of scrimmage. Positioning varies by level and crew mechanics.
Head Linesman / Down Judge (H or DJ)
This official works along one sideline near the line of scrimmage and monitors assigned line play, formations, and sideline action.
The position is traditionally known as the head linesman in many high school systems. Other levels may use the title down judge.
Responsibilities may include working with the chain crew and helping determine the line to gain.
Line Judge (L or LJ)
The line judge operates on the opposite sideline and is responsible for assigned action near the line of scrimmage, sideline rulings, and coverage during running and passing plays.
Additional responsibilities depend on the crew size and governing mechanics.
Back Judge (B or BJ)
The back judge provides deep-field coverage and observes assigned receivers, defenders, passing action, and kicking plays.
Timing and goalpost responsibilities vary by crew configuration and rule code.
Side Judge (S or SJ)
The side judge typically works downfield on one side of the field in larger crews.
Responsibilities may include receiver and defender coverage, pass interference, sideline rulings, and designated kicking-play coverage.
Field Judge (F or FJ)
The field judge provides deep-field coverage on the opposite side from the side judge.
This official monitors assigned passing action, sideline plays, receivers, defenders, and designated kicking situations.
Crew assignments vary: Officials should consult the approved mechanics manual for their association rather than assuming every crew uses identical positioning or responsibilities.
Essential Football Referee Equipment
Football officials rely on specialized equipment to communicate decisions, track game information, mark important spots, and perform their duties efficiently.
Football Referee Whistles
A whistle is one of the most recognizable pieces of officiating equipment.
Officials use whistles to communicate that play has ended or to stop action when required by the rules and mechanics.
Common options include:
-
Finger-grip whistles.
-
Traditional handheld whistles.
-
Whistles worn with a lanyard where permitted.
-
Pealess whistles designed for consistent sound.
Many officials prefer the Fox 40 style of pealess whistle because of its distinct sound and practical design.

Football Penalty Flags
Penalty flags are used by officials to indicate observed fouls during a game.
Traditional football penalty flags are yellow and generally include a weighted portion to assist with placement.
Important considerations include:
-
Appropriate flag weight and construction.
-
Secure storage in the waistband or pocket.
-
Reliable access during play.
-
Carrying a second flag when preferred or required.
Officials should use safely constructed flags appropriate for their association and avoid hazardous weighting materials.

Football Referee Bean Bags
Bean bags are used to mark specific spots on the field that may be important for enforcement or game administration.
They are commonly used in situations involving fumbles, kicks, and other plays requiring a spot to be marked.
Bean bags are available in multiple colors, including black, blue, and white.
The appropriate color and use depend on association requirements and officiating mechanics.

Down Indicators
A down indicator is a small elastic wrist accessory that helps officials keep track of the current down.
Many designs feature a finger loop that can be moved between fingers to identify first, second, third, or fourth down.
Some officials also use a separate indicator to remember ball placement between the hash marks.

Common styles include fitted, adjustable, and performance-fabric caps.
Officials should confirm the approved cap style and piping requirements with their association.
Choosing the Right Football Referee Uniform
A professional football referee uniform should provide comfort, mobility, visibility, and consistency with the requirements of the officiating organization.
Uniform requirements vary by level, association, and assignment.
Football Referee Shirts
Modern football referee shirts commonly feature black-and-white vertical stripes.
