In an effort to eliminate a potential timing advantage gained by the defensive team in high school football, the play clock will be set to 40 seconds – effective with the 2020 season – when an official’s time-out is taken for an injury to a defensive player or a defensive player has an equipment issue.

This change was one of six rules revisions recommended by the National Federation of State High School Associations (NFHS) Football Rules Committee at its January 12-14 meeting in Indianapolis. All recommended changes were subsequently approved by the NFHS Board of Directors.
