INDIANAPOLIS, IN (February 14, 2011) — A change in the definition of a chop block in high school football, along with a strong emphasis on proper use of the helmet to minimize risk of injury, highlighted the January 21-23 meeting of the National Federation of State High School Associations (NFHS) Football Rules Committee in Indianapolis.

The modification of the chop block rule was one of 11 rules changes recommended by the Football Rules Committee and approved by the NFHS Board of Directors.

The new language in Rule 2-3-8 defines a chop block as “a combination block by two or more teammates against an opponent other than the runner, with or without delay, where one of the blocks is low (at the knee or below) and one of the blocks is high (above the knee).”
