What's on the score bug in the corner of the screen?
The score bug shows both teams and their scores, the quarter, the game clock, usually the play clock, down and distance, how many timeouts each team has left, and an indicator of which team has the ball.

What do the dots or bars under each team mean?

Is the yellow line actually on the field?
No. The yellow first-down line is a computer graphic drawn into the TV picture, first used on a 1998 ESPN broadcast. Players and officials can't see it.

How do officials measure for a first down now?
Since 2025 the NFL has used a virtual measurement system instead of the old chain-stretch measurements. Officials still spot the ball and mark the line to gain by hand.

Why is the clock still running after a tackle?
If the ball carrier is tackled in bounds and nothing else stops the clock, it keeps running while teams line up. That's why teams that are ahead late keep running the ball.

What's the difference between a fumble and an interception?
A fumble is when a player with the ball loses it, and either team can recover. An interception is when a defender catches a forward pass. Both are turnovers.

What is "down by contact"?
A runner is down once a defender's contact causes any part of his body other than his hands or feet to touch the ground. The play ends there even if he gets back up.

Why did they stop the game to look at a replay?
Either a coach threw a red challenge flag, or the replay official started a review (on scores, turnovers, plays after the two-minute warning and in overtime). The referee announces the result over his microphone.

What do the referee's arm signals tell me at home?
Arms straight up mean a score. Folded arms mean a penalty was declined. Clutching the wrist means holding. You can follow most penalties from signals before the announcement.

Why do teams go for it on fourth down?
If the offense makes the line to gain on fourth down, it keeps the ball. If it fails, the other team takes over right there. So coaches weigh field position against the chance to keep the drive going.
