"The play clock will continue to start at 25 seconds ... (e) following an official’s time-out, with a few exceptions."
The Rules Book lists 12 types of official's time outs. Could someone who knows for sure post which ones are the exceptions?
Here's the rule (2017 book). The only one that will be 40 sec is a first down.
Easy way to think about it is if we interrupt the natural flow of the game (administrative stoppage), it goes to 25. So if the team can't snap the ball because we as officials are doing something, then it's 25.
a. For measurement of a possible first down.
b. When a first down is declared. c. Following a change of team possession.
d. When captains and coaches are notified of the time remaining.
e. For a player in need of equipment repair.
f. To dry or change the ball.
g. For unusual heat or humidity which may create a health risk to the players.
h. When a coach-referee conference concerning the misapplication of a rule
results in the referee altering his ruling. (3-5-1 1 )
i. After a foul, to administer the penalty.
j. For any unusual delay in getting the ball marked ready for play.
k. For a TV/radio time-out that is permitted and granted as authorized by state
association policy.
l For a one-minute intermission between the first and second and the third
and fourth periods and following a try, successful field goal or safety and
prior to the succeeding free kick.
