Middle and high school football 34 U.S. states have implemented a mercy rule for middle or high school football, commonly involving a "continuous clock" timing mechanism whereby the game clock continues to run during most stoppages, such as incomplete passes or plays out of bounds. This rule is typically triggered when one team gains a substantial lead during the second half of the game. For example, in 2022,
Louisiana adopted a variation of this rule, instituting a running clock when the point differential reaches 42 at any point during the game. This greatly decreases the amount of time to complete the game, which reduces the leading team's chances to score more and the time the trailing team must spend facing an insurmountable deficit. In most states, the clock stops only for scores, timeouts (officials', injury, or charged), or the end of the quarter. Plays that normally stop the clock, such as penalties, incomplete passes, going out of bounds, or change of possession, do not. The rule varies by state; for example, the clock does not stop upon a score in
Colorado,
Indiana,
Kansas (regular-season games only), or
Missouri (fourth quarter only). In most states, if the point differential is reduced below the mercy rule-invoking amount, normal timing procedures resume until the end of the game or the mercy rule-invoking point differential is reestablished; in Colorado, Georgia, Kansas and Louisiana, the clock continues to run even if the differential falls below the threshold. Most states with mercy rules waive this rule for championship games. In some states, coaches and game officials may choose to end a game at their own discretion 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 losing team 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 prohibiting a team with a very large lead from running certain plays 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 require 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 be shortened to 12 minutes each. The coaches also request that the second half be played with a 'running clock' i.e., that the game clock not be stopped." The NCAA Football Rules Committee determined, "The remaining quarters may be shortened to 12 minutes each. However, the 'running clock' is not allowed; normal clock rules apply for the entire game." The shortened game resulted in some
sportsbooks voiding bets due to house rules requiring 55 minutes of play for the game to count. On September 7, 2024, the
Georgia Bulldogs led the
Tennessee Tech Golden Eagles 45–0 at the end of the third quarter. Both coaches agreed to shorten the fourth quarter to ten minutes. The final score was 48–3. On August 29, 2024, the
Arkansas Razorbacks led the
Arkansas–Pine Bluff Golden Lions 49–0 at halftime. By mutual agreement, the coaches agreed on ten minute lengths for the third and fourth quarters. The final score was 70–0, and some sportsbooks voided bets due to an insufficient game length. October 1, 2022, when the
Syracuse Orange played the
Wagner Seahawks. The mismatched Wagner team trailed the 4-0 Syracuse team 49–0 at halftime. In the second half coaches and the referee agreed to 10 minute quarters. Syracuse head coach Dino Babers made the controversial choice of leaving some of Syracuse's starting players in late into the second half. The final score of the game was 59–0. September 21, 2019,
Ohio State was leading
Miami (OH) 76–5 in Columbus, Ohio with 2:40 left in the 4th quarter when the game was temporarily suspended due to lightning. Both coaches agreed to end the game with the final score standing as is. September 1, 2018, the rule was enacted during a game Georgia played against Austin Peay in Athens, Georgia. With the score 45–0 in the 3rd quarter and a high
heat index, Austin Peay Coach
Will Healy suggested to Georgia head coach
Kirby Smart that they play a 10-minute fourth quarter instead of the typical 15-minute quarter. The coaches and referee agreed and the game was shortened. September 24, 2016, the
Missouri Tigers led
Delaware State 58–0 at halftime. The coaches agreed to shorten the third and fourth quarters from 15 minutes to 10 minutes each, shortening the total game time from 60 minutes to 50 minutes. Missouri added three touchdowns in the abbreviated second half to make the final score 79–0, setting team records for the most points scored in a game (79), the greatest margin of victory (79), and the largest number of touchdowns scored (11). Also in 2016, the game between
Clemson and
South Carolina State had both the third and fourth quarters shortened from 15 minutes to 12 as a result of Clemson leading the game at half 45–0. The final score of the game was 59–0. Earlier in 2016, the game between
Texas State and
Arkansas saw the fourth quarter shortened to 10 minutes when severe thunderstorms were approaching
Donald W. Reynolds Razorback Stadium. Arkansas led 42–3 at the end of the third quarter, and the final period was scoreless. A similar scenario took place in 2017 in the game between
TCU and
Kansas, where the coaches agreed to a running clock for the final 12:49 of the game due to severe thunderstorms approaching
Amon G. Carter Stadium. In a 2013 game,
Old Dominion University (ODU) was losing to the
University of North Carolina (UNC) 80–20 when ODU coach
Bobby Wilder asked for the fourth quarter to be shortened by five minutes, which UNC coach
Larry Fedora agreed to. Fedora also directed his quarterback to take a knee on fourth and goal with 1:53 remaining to not run up the score. In a 1988 game,
Kansas Jayhawks coach
Glen Mason asked if a running clock could be used after his team trailed 49–0 at halftime to the
Auburn Tigers. Auburn coach
Pat Dye and the officials agreed, and Auburn ended up a 56–7 winner. In 2015, another shortened game occurred when the
Boston College Eagles dominated the
Howard Bison 62–0 by halftime. The coaches agreed to remove five minutes from each quarter of the second half of the game. Despite the NCAA Football Rules Committee's subsequent ruling (A.R. 3-2-2-I) that a "running clock" is not permitted, a continuous clock was used September 5, 2013, beginning in the fourth quarter when the
Georgia Tech Yellow Jackets had a 63–0 lead against the
Elon Phoenix. That was at the request of Elon coach
Jason Swepson and agreed upon by Georgia Tech coach
Paul Johnson. Georgia Tech won the game 70–0. However, in the Mississippi Association of Community and Junior Colleges, a running clock is allowed if the team is ahead by 38 points or more. This rule, unique only to the MACJC, was instituted in 2013. ==Football==
