Rule 8-3-1 states that “points shall be scored according to the point values in Rule 8-1-1 if the try results in what would be a touchdown, safety or field goal under rules governing plays at other times.”
In 1988, the NCAA introduced a rule which allowed defenses to return a failed point-after try or two-point conversion for points. This created the possibility of a truly strange occurrence: the one-point safety. It has happened only five times in college football since 1988, and only twice at the FBS level—in the 2004 Texas-Texas A&M game and the 2013 Fiesta Bowl between Kansas State and Oregon.
How does it occur? If the defensive team gains possession of the ball on a point-after try and is tackled in the end zone, the offense receives one point. In the Fiesta Bowl, Oregon botched the point-after try with a K-State defender grabbing the ball. Retreating backward into the end zone, he attempted a lateral to a teammate, who was tackled by Oregon. One point, Ducks.
