NFL Debuts Hawk-Eye Virtual Measurement System at Hall of Fame Game

Hall of Fame Game viewers experienced a precise first-down call from the Hawk-Eye measurement system, which will replace the chain gang as the NFL’s primary measurement tool in 2025.

Overview

  • The Hawk-Eye system’s first virtual measurement occurred in the second quarter after Lions RB Craig Reynolds’ 10-yard run, pausing play briefly to project the line to gain.
  • Powered by six 8K cameras, the technology is operated from the NFL’s Art McNally GameDay Central in New York and integrates with existing replay infrastructure.
  • The process completes in about 30 seconds, saving up to 40 seconds compared with the traditional chain crew measurement.
  • Chain crews remain on the sideline as a backup measure and officials continue to manually spot the ball.
  • Media and fans offered mixed feedback, with some praising the speed and precision and others lamenting the diminished role of the chain gang.
