Nashville Sports Leagues - Coed Flag Football
Rules listed here are modified from NIRSA Rules

GRACE PERIOD
Game time is forfeit time. There is no grace period.

NUMBER OF PLAYERS
COED SCREEN
Games shall be played with 4 men and 2 women.

NUMBER OF PLAYERS TO START AND FINISH
Teams may begin and end a game with four players (minimum of 1 female). There must not be more than four men on the field at any one time. Playing with 3 or less players at any time will result in a forfeit. Teams may "pick up" during the regular season (NSL members only with accepted roster/waiver on file). You may not pick up more than the number of players needed to be at full strength. 

COIN TOSS
The team winning the coin toss can:
Choose to receive the first half or the 2nd half. The opposing team will then choose a direction to defend. One team cannot start both halves with possession.

GAME CLOCK
The length of the game is 40 minutes, divided into two halves of 20 minutes. Running time with no clock stoppage is used for the first 19 minutes of each half. During the final 1 minute of each half traditional clock stoppage is used. The playoffs will have a 2-minute warning.


COED GAME CLOCK
During the final minute of each half all plays will be open-open requiring no play to be gender specific.

PLAY CLOCK
A 25 second play clock will start once referee blows his whistle readying the ball for play.

TIME OUTS
Each team receives two timeouts per half. Each time out is thirty-seconds. During the first nineteen minutes of each half the game clock will start once the time out is over and the ball is readied for play (only during regular season). During regular season only one timeout can be used inside the one-minute warning.

MERCY RULE
At the 1-minute warning the game will be ended by mercy rule if either team holds an advantage of 25 or more points. Also, the maximum point differential recorded of any game will be capped at 25 points. 

OVERTIME
Overtime is decided by extra point attempts. Teams will choose to try for 1, 2 or 3. Team 2 is not required to choose same extra point try as Team 1.

HURRY UP RULE
After scoring, the scoring team can elect to give the opposing team the ball at the 20-yard line in order to keep the opponent from using up the clock. Once this is declared, the scoring team must give their opponent the ball at the 20-yard line until the end of the game. This hurry-up tactic becomes irrevocable right of the opponent. This rule only applies after scoring plays. In the case of turnover on downs or an interception by the defense ball will be spotted at the end of the live play. 

EQUIPMENT
- Mouthpieces are suggested
- No hard billed hat will be worn
- No metal cleats
- No pockets are allowed (you will not be able to play with pockets and you will not be allowed to tape pockets)
- Football must be provided by the teams. High school, collegiate or NFL size footballs are the only acceptable sizes allowed.

SPOT OF BALL
The spot of the ball is the location of the ball at the time of the flag belt removal (broken clip) or one hand touch in the appropriate scenario.

BLOCKING
BACKFIELD BLOCKING: The blocker in the backfield may shield a defender with no separation of the arm(s) from the body. A blocker is allowed to move (shuffle) left, right or backwards. The blocker may not initiate contact with the rusher. A blocker may not run a route under a rusher to impede the rusher's route to the quarterback.

DOWNFIELD BLOCKING: A basketball style (non moving) screen is the only acceptable form of downfield blocking. A blocker may shield a defender with no separation of the arm(s) from the body. The blocker also may not run between a rusher and ball carrier impeding a defenders progress to the flag.

OFFENSIVE FORMATION
Only 1 player is required to be on the line of scrimmage (center).

GENDER PLAYS
A female must be involved in a play at least once every 3 plays. Being involved is considered:
- Being the quarterback and attempting a pass beyond the line of scrimmage
- Advancing the ball beyond the line of scrimmage
- Being the intended receiver of a pass
- Possession of an intended pass supersedes the intent of the play and will be ruled a non-gender play.
- Gender plays are not in effect for extra points.

MALE OPERATIVE PLAY
A male is not allowed to gain possession of the ball behind the line of scrimmage and advance the ball beyond the line of scrimmage. (Not applicable during the final 1-minute remaining in each half)

Rushing the Quarterback
Any defensive player lined up behind the 3-yard neutral zone can rush the quarterback on the snap.

NO RUN ZONE
COED
No running plays are allowed within three yards of the goal line.

SNAP
Any offensive player can receive the snap as long as they are 2 yards behind the line of scrimmage.

LEGAL POSSESSION
The receiver must have one foot in bounds for a legal reception. If a player steps out of bounds on his own he cannot re-enter play.

QUARTERBACK
The quarterback is defined as the player attempting a legal forward or lateral pass behind the line of scrimmage. A flag pull in the act of throwing the ball (prior to release) by the quarterback will be considered a sack.
