Illegal motion explained: The Detroit Lions had an opening drive touchdown taken off the board on a David Montgomery to Jared Goff 1-yard touchdown reception, but it was negated due to an illegal motion penalty referee Craig Wrolstad explained after the game.
"There were a lot of moving parts on that play," Wrolstad said via a Kansas City pool report. "We had a quarterback go up to the line of scrimmage. He paused momentarily in the quarterback position, didn't get under center, but he walked up and stopped like he was the quarterback. Then, he went in motion, and they threw the ball to him for a touchdown.
"If the quarterback assumes the quarterback position and then goes in motion, he has to then stop for a second before they snap the ball. Because he gets out of the view of some of the officials, we had to piece it together as a crew as to whether he stopped initially and then whether he stopped when he went in motion. It was determined after a lengthy discussion that he stopped at the quarterback position and then went in motion. But when he does that, he has to stop when he goes in motion."
