All about penalties
During the game it’s likely that a team will break a rule and get a penalty. You may see the referee throw down a yellow flag, his hat, or a beanbag. It’s hard to keep up with the many penalties in football, but if you listen to the referee, you will be able to hear the penalty that was caught and the resulting enforcement. Depending on the whether the team is playing defense or offense, the enforcement could be a lost in yards, gain yards, or an automatic first down.
