Often there are two choices available: ignore the foul and let the play stand, or take the penalty from where the play started and disregard the play. There are some penalties that do not need to be accepted; those that are measured after the play, from where the new down occurred. A team might accept the penalty if they had lost yards on that play or if the penalty would give them an automatic first down where they had not achieved it. They might decline if the position from the penalty is worse than where the down occurred or if they scored from that play. Often the referee will assume the team will choose the more advantageous field position and act accordingly, but they usually confirm with the captain before announciing it.
