NFL to use Hawk-Eye technology for first down measurements, phasing out chains

The NFL is modernizing how first downs are measured during games. Starting in the 2025 season, the league will replace the traditional chain measurement with Hawk-Eye virtual technology to determine if a first down has been achieved. Chain measurements will still be used as a secondary method alongside the new technology-driven system.

Kimberly Fields, NFL senior vice president of football operations, explained that Hawk-Eye technology underwent "extensive testing" throughout 2024, including during the preseason, to assess its effectiveness as a replacement for the outdated method. Apparently, the NFL is confident enough in the results to proceed with the update.

The new system utilizes stadium cameras to track the ball and players, automatically notifying officials when a first down is achieved. However, the early plan is for officials to still manually spot the ball after each play.

The goal is to streamline the measurement process and reduce controversial on-field calls. The NFL will test broadcast and in-stadium graphics to help fans better understand the new system.

At the NFL Scouting Combine this week, Washington Commanders head coach Dan Quinn expressed his support for the change.

"Especially if we can, like, more efficiently mark it," Quinn commented. "And then the game keeps going, and we keep rocking."
