illegal motion
Prohibited player movement
Illegal motion is a penalty in American football for movement by an offensive player that violates formation rules—typically moving toward the line of scrimmage before the snap, or having two players in motion simultaneously.
The violation results in a five-yard penalty: The referee flagged the receiver for illegal motion.
