Lions illegal motion on Jared Goff TD, explained

Detroit got off to a strong offensive start, with Jahmyr Gibbs totaling 32 rushing yards on the opening drive as Jameson Williams caught a pair of passes. Gibbs failed to punch the ball past the goal line on three-straight attempts though, setting up 4th & Goal from the one.

After taking a timeout, Campbell called for a trick play -- running back David Montgomery, a high school quarterback, took the snap. He threw to his left, where Goff bobbled the pass, then secured it and followed a blocker into the end zone.

For a moment, the Lions appeared to take a 6-0 lead on a nice play. Until the officials came together, ruling to nullify the play after it was over.

Goff was called for illegal motion upon the officials' conversations. Because he was under center, he had to stop and establish himself as a receiver, which he did not do. Had Goff paused for a moment to establish himself, instead of staying in motion, the play would have been fine.

"After discussion, the quarterback never got set, therefore it is illegal motion," referee Craig Wrolstrad said.

The Lions wound up kicking a field goal after the penalty, taking a 3-0 lead instead of the potential 7-0 lead. And on the following drive, the Chiefs answered with an Xavier Worthy touchdown.

What is illegal motion?

Here is how the NFL defines its illegal motion rules:

"When the ball is snapped, one player who is lined up in the backfield may be in motion, provided that he is moving parallel to or away from the line of scrimmage. No player is permitted to be moving toward the line of scrimmage when the ball is snapped. All other players must be stationary in their positions.

If an eligible receiver who is on the line moves to another position on the line (not forward), he must come to a complete stop prior to the snap. If he does not come to a complete stop, it is Illegal Motion.

It is also illegal motion if a T-Formation Quarterback goes in motion and fails to come to a complete stop for at least one full second prior to the snap."
