A61’s foul is a personal foul. RULING: Penalise Team B five yards for B60’s offside, then penalise Team A 15 yards and reset the line-to-gain indicator to

V. After Team A has made a first down, the umpire has placed the ball on the ground at the B-30.
The referee waves the umpire away from the ball but before he signals the ball ready for play, snapper A55 snaps the ball. RULING: Team A dead-ball foul for delay of game.
Five-yard penalty, first and 10 at the B-35. NOTE: This is a foul between series in that it takes place before the ball is declared ready for the next series. Hence it is first and 10, not first and 15 (Rules 4-1-1, 4-1-4). [Cited by 5-2-7-b]
