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.

Be the Referee: Bowling Ball Bounces Out of Gutter

Below is this week's segment – Bowling Ball Bounces Out of Gutter - Listen

We’ve got a bowling ball in our hands today – and we’re ready to deliver our first ball of the third frame.

It’s not a great roll, but it’s a powerful one. The ball goes into the gutter but bounces out and then knocks over seven pins.

Lucky break, right?

Not exactly. Once the ball is in the gutter, it’s a dead ball. Any pins knocked down by the ball’s return don’t count. If it happens on the first delivery, the pins knocked down by the rebound are reset for the second delivery.

Now if a pin bounces completely out of the pit area and returns to knock down any standing pins, that counts.

But if your ball goes into the gutter, that’s it – you can’t count any pins knocked down if the ball bounces out.
