Overview
- League officials now use virtual measurements powered by Hawk-Eye, targeting roughly 30 seconds per ruling versus about 75 seconds with chains.
- Stadium setups include six 8K cameras, and Sony says the system can measure to within less than half an inch.
- On‑field officials still spot the ball, teams may challenge spots, and the replay booth makes the final determination on placement.
- Traditional chain crews stay on the sideline as a secondary option even as virtual measurements become the primary method.
- After testing during the 2024 season and a first in-game use at July’s Hall of Fame Game, the system is fully deployed for 2025.
