New rules on blindside blocking are the most recent steps taken by the National Federation of State High School Associations (NFHS) Football Rules Committee in minimizing the risks associated with the sport.
The establishment of a new definition of a blindside block in Rule 2-3-10 and the addition of Rule 9-4-3n prohibiting a blindside block were two of 11 rules changes recommended by the NFHS Football Rules Committee at its January 20-22 meeting in Indianapolis. All rules changes were subsequently approved by the NFHS Board of Directors.
