Editing Eligible receiver (section)

==High school==
In [[high school football]], the rules of eligibility are roughly the same as in the college game. However, as of February 2009, at least five players must wear numbers between 50 and 79 on first, second, or third down, which by rule would make them ineligible receivers. This was because of a change in the definition of a scrimmage-kick formation made by the [[National Federation of State High School Associations]] (NFHS).<ref name="hsban">{{cite press release |url=http://www.nfhs.org/web/2009/02/horsecollar_tackle_to_be_penali.aspx |title=Horse-collar Tackle To Be Penalized in High School Football |publisher=NFHS |date=February 13, 2009 |access-date=February 1, 2015 |archive-url=https://web.archive.org/web/20090219202557/http://nfhs.org/web/2009/02/horsecollar_tackle_to_be_penali.aspx |archive-date=February 19, 2009 |author=Colgate, Bob}}</ref> The change was intended to close a loophole in the rules which allowed teams to run an [[A-11 offense]], in which a team would be exempted from eligibility numbering restrictions if the player receiving the snap was at least seven yards behind the line of scrimmage.<ref name="espn">{{cite web |url=https://www.espn.com/espn/page2/story?page=weinreb/080811&lpos=spotlight&lid=tab4pos1 |title=The A-11 offense: Ridiculous, or genius? |publisher=[[The Walt Disney Company]] |work=[[ESPN.com]] [[Page 2]] |date=August 28, 2008 |access-date=February 1, 2015 |author=Weinreb, Michael |archive-url=https://web.archive.org/web/20080903131422/http://sports.espn.go.com/espn/page2/story?page=weinreb%2F080811&lpos=spotlight&lid=tab4pos1 |archive-date=September 3, 2008 |url-status=live}}</ref>

In 2019, the NFHS changed the rules slightly, instead measuring the number of players behind the line of scrimmage, limiting that number to four. The minimum number of players on the offensive line was reduced from seven to five.<ref>{{cite web| url = http://www.nfhs.org/articles/40-second-play-clock-postseason-instant-replay-among-football-changes/| title = "40-Second Play Clock, Postseason Instant Replay Among Football Changes"}}</ref>
