In any penalty, "loss of a down" means that the down upon which the foul occurred has used up one of the permissible series of consecutive downs.
In any penalty where there is a loss of yardage, there shall be no loss of down.
EXCEPTION: Major Foul (See Rule 7, Section 2)
When a foul has been committed on any play, the non-offending team shall be entitled to the penalty or the option of declining the penalty to take any advantage of position, score, down, time, etc. The non-offending team may decline a score to take advantage of a penalty or may decline a penalty to permit a score by the offending team to stand.
In certain cases, where so stated, a penalty shall be applied without option.
