A first down in football is when the offensive team gains 10 yards, resetting the down counter. The 10 yards required for the first down are marked by yard markers held by officials, sometimes called the marker or the chains. A first down can only be obtained from a play beginning at the line of scrimmage, where the ball is placed. A first down can also occur after a penalty which may reset the down counter or give the offensive teams more than the 10 yards required for the first down. But what happens if the touchdown is scored on the first down?
According to the NFL Guide for Statisticians, a touchdown is recorded as a first down, regardless of the distance gained on the play, in addition to being recorded as a touchdown.
