Rules
In addition to those practical purposes, gradually, some rules have evolved that are unique to the final two minutes of each half and overtime. There is no special event at the ends of the first and third quarters, aside from swapping end zones, so there is no two-minute warning then, only at the halves.
The two-minute warning in the fourth quarter is an important milestone in the game for a team that is in the lead and looking to run out the clock. If the leading team has the ball on first down with less than two minutes to go in the game and the opposing team has no timeouts remaining, the quarterback can often safely end the game by "taking a knee" three times in a row without risking injuries or turnovers. This is because at the end of each play, the offensive team can take up to 40 seconds to start running the next play.

Famous quotes containing the word rules:
“This was Pharaoh, direct descendent of our deity Amon, god of the sun, who rules the heavens as Pharaoh rules the earth. Again, he brought treasure, gold, and precious jewels taken from our enemies. For to Pharaoh riches were power and power was to be desired. And also again he brought many captives. For is it not by slaves that one becomes even richer and then has even more power?”
—William Faulkner (1897–1962)
“Here was a place where nothing was crystallized. There were no traditions, no customs, no college songs .... There were no rules and regulations. All would have to be thought of, planned, built up, created—what a magnificent opportunity!”
—Mabel Smith Douglass (1877–1933)
“Unfortunately, we cannot rely solely on employers seeing that it is in their self-interest to change the workplace. Since the benefits of family-friendly policies are long-term, they may not be immediately visible or quantifiable; companies tend to look for success in the bottom line. On a deeper level, we are asking those in power to change the rules by which they themselves succeeded and with which they identify.”
—Anne C. Weisberg (20th century)
