General Fouls
A 10-yard penalty occurs when a foul is committed.
If a thrower is in a throwing motion, all contact initiated by a marker is a foul.
A thrower may not push or pivot into the body of a marker in a legal marking position.
A thrower may not initiate contact with a marker by vigorously swinging an elbow.
Contact on the follow through after the throw is not a foul.
