9-yard marks

Illegal substitution still could be called if there is a substitution not completed by a player not coming inside those "tick marks." Illegal Formation would apply if no substitution is made (or has been completed) and a player never comes inside the marks.

The 9-yard marks have nothing to do with illegal substitution. It's clearly an illegal formation call as previously stated.
