stop upon a score in Colorado, Indiana, Kansas (regular-season games only), or Missouri (fourth quarter only). In most states, once the point differential is reduced to below the mercy rule-invoking amount, normal timing procedures resume until either the end of the game or the mercy rule-invoking point differential is re-established; in Colorado, Georgia, Kansas and Louisiana, the clock continues to run even if the differential falls below the threshold. Most states that have mercy rules waive this rule for a championship game. In some states, coaches and game officials may choose to end a game at their own discretion at any time during the second half if the continuous clock rule is in effect; that usually happens if a lopsided margin continues to increase or if threatening weather is imminent. Sometimes the coach of the team that is losing agrees to shorten the length of a quarter in addition to the continuous clock rule. Although it is rare, some states or high school conferences have rules in which the team with a very large lead may not run a certain play for the rest of the game, such as a deep pass or outside run. In some states (where 8-man and 6-man football is widely used), the rules call for a game to end when one team is ahead by a certain score (like 45 or 50 points) at halftime or any time thereafter. In other states with 6- or 8-man football, continuous clock rules are used, and the rule may be modified; for instance, in Iowa, the rule goes into effect if the 35-point differential is reached at any time after the first quarter. In a variant on the mercy rule used in Connecticut high school football from 2006 to 2016, the team's coach was issued a one-game suspension (i.e., for the team's next game) if at any point the team had a 50-point lead. In 2016 it was replaced with a running clock rule. College football The National Collegiate Athletic Association's mercy rule provides, "Any time during the game, the playing time of any remaining period or periods and the intermission between halves may be shortened by mutual agreement of the opposing head coaches and the referee." (NCAA Football Rule 3-2-2-a) NCAA Football Approved Ruling 3-2-2-I cites an example: "At halftime the score is 56–0. The coaches and the referee agree that the third and fourth quarters should
