Below is this week's segment - Sideline Safety - Listen
Safety in football continues to be a hot topic. We have talked previously here about rules that have improved player safety. Today we’re going to focus on the adults - specifically coaches and officials that work at the sideline area just in front of the team box.
The rules require that from the time just before the snap until the end of the play, all coaches and team personnel must be completely out of the 6-foot safety zone located in front of the team box at each sideline. This then gives the official plenty of room to work unimpeded in either direction.
Now as soon as the play ends, coaches can move into this area to instruct their players or send in the next play and then move back prior to the next snap.

Below is this week's segment – Illegal Substitution/Participation - Listen
We’re on the football field this week with 23 players.
Twenty-three is one too many; there should only be 22 on the field at once – 11 on offense, 11 on defense.
But on this play, the offense had a 12th player lined up on the field.
What’s the call?
It depends on when the penalty is spotted.
If the officials catch it before the play is run, that’s an illegal substitution and a 5-yard penalty.
But if the ball is snapped and a play is run with 12 on the field – and the 12th player is not attempting to get off the field – then it’s illegal participation and a 15-yard penalty. It’s also a 15-yard penalty if the offense uses a substitution to create a deception.
