"I will advise them not to use it again, that is correct", National Football League vice president of officiating Al Riveron said Thursday in a conference call with reporters. "That is correct. I've already done that".
Steratore took a piece of paper out of his pocket and stuck it between the ball and the yardstick to confirm what he says he already saw, a first down for the Cowboys.
It didn't, and the Cowboys were awarded a first down.
Steratore later said in a pool report that he used the paper as "nothing more than a reaffirmation".
"When he did bring out the piece of paper, that was very, very unusual", Riveron said on a conference call with reporters Thursday.
"Geno made the decision strictly, strictly by visual affirmation that the ball had made the line to gain", Riveron said. Officials have been told not to use paper anymore. "I'm not happy with the way things were done", Del Rio said after the game.
Fans shared Del Rio's frustration.
"I don't want to get fined, OK?"
