Whenever you suffer a major

for enough injury to cause a shock
penalty (see Shock, p. 419), you must
make an immediate HT roll to avoid
knockdown and stunning.

Technical Grappling recently included the neck as a sub-part of the head location. Is that only for grappling purposes, or should it apply for this rule too? For what it's worth, a blow that caused shock penalty hitting my neck does sound to me like it might plausibly force that HT roll too.
