Anderson said that the league will be using the same procedures that apply during the postseason, at which time the eighth official has a direct line to the supervisor in the booth. The eighth official then can relay information immediately to the seven officials who are directly working the game. If, for example, the officials are going to spot the ball in the wrong place or march off too many (or too few) penalty yards, the supervisor will let the eighth official know.
I guess the NFL doesn't trust them either . . .
