The ranks of the NFL’s game officials will be changing in 2017, at least by a little bit.

The NFL Referees Association have announced that three officials have retired: Head Linesman John McGrath (pictured); Line Judge Troy Veteri, Jr.; and Field Judge Bob Waggoner.

Veteri has 25 years of experience. Waggoner, 20. McGrath has been on the job for 15 seasons.
