The 15-yard penalty that is applied from the receiving team’s 20-yard line. The rules also states that a fair-catch kick is technically different from a free kick.
The NFL explicitly declares that a fair-catch kick “is not a free kick” and only views kickoffs, safety kicks, and onside kicks as free kicks.
Additionally, Rule 10, Section 2, Article 5 states that “the following will happen if time runs out during a play in which a player has signaled for a fair catch: After any relevant penalties are enforced,
The receiving team may choose to prolong the time by trying a fair catch kick or by snapping from scrimmage if the kicking team interferes with a receiver who has signaled for a fair catch.”
History of fair-catch kicks Since Joey Slye’s fair-catch kick against the Tampa Bay Buccaneers in 2019 with the Carolina Panthers, Dicker’s kick was the first attempt at one.
