NFL referees group adds 4 members to start work in 2017

All four took part in the NFL's Officiating Development Program. Oliver and Rogers last officiated games in the Southeastern Conference, while Carr worked in the Big Ten and Dickson in the Pac-12.

"It's a long, tough road to become an NFL official," said Scott Green, NFLRA's executive director. "We congratulate these four outstanding individuals on their selection and welcome them to the union."

The new officials will help fill in with the recent retirements of head linesman John McGrath, line judge Tony Veteri, Jr., and field judge Bob Waggoner.
