Crack Back Block

What constitutes an illegal crack back block? I've seen plays where, at the snap, a split end moves down the line toward the ball and blocks an unsuspecting defensive end. Under what circumstances is that legal?

Thanks

It's only legal if the defender is hit in the side or the front above the waist.

Below the waist or in the back is illegal.

BTW, it doesn't make a tinker's damn whether the blocker's head is in front or not.
