"NFL Explores High-Tech Replacement for First-Down Chains"

The NFL is considering replacing the traditional chain measurements for first downs with optical tracking technology after successful testing at several stadiums. While there is some interest from teams and owners, outfitting all 30 NFL stadiums with the technology for next season may be a challenge. The proposed technology, developed by Hawk-Eye, would need to be approved by the competition committee and voted on by the owners. Additionally, the league is also exploring the use of high-resolution cameras and smartwatches for instant replay decisions and delay of game issues.
