[Spence]

Explain the sideline infraction to me. I'm listening to a high school game and a team scored on a 90 yard screen pass. However, the announcers said that a sideline infraction was called on the team that scored and the TD was taken off the board.

I'm not complaining since my team came out on the good side.

Is there a warning first?

How is it enforced? From the LOS?

Is it unusual to call more than once in a game? Two have been called so far on the same team.
