Overview

• Special teams rules shift as touchbacks on kickoffs now place the ball at the 35, bounces into the end zone go to the 20, and trailing teams can declare onside kicks at any time from the 34.
• Regular season and postseason overtime are aligned with each team guaranteed a possession in a 10‑minute period after a three‑minute intermission, with next score winning if still tied after both possessions.
• Replay officials gain broader authority to assist on objective elements and certain penalties, including spot of the ball, complete or incomplete passes, possession of loose balls, clock administration and roughing‑the‑passer to the head or neck.
• Hawk‑Eye virtual measurement becomes the primary first‑down spotting system using six high‑definition cameras per stadium to determine ball placement and reduce reliance on chains.
• Conduct enforcement tightens as the league adds the “nose‑wipe” gesture to unsportsmanlike celebrations that draw a 15‑yard penalty.
