With so much uncertainty surrounding the 2020 college football season, many fans have wondered if they’ll be sitting in a stadium this fall. According to CBS Sports, one group of people used to working in-stadium could instead be working remotely this season.

Dennis Dodd reports that “discussions have begun to allow replay officials to potentially work games virtually this season due to the coronavirus.”

National coordinator of officials Steve Shaw, formerly of the SEC, said some officials may be in higher-risk categories and unable to travel by plane to college football games.

“You hear from medical professionals. If you’re in that at-risk group, you have to think more about protecting yourself,” Shaw told CBS. “If you have an on-field crew that’s all having to get on a plane, maybe that’s OK. But if you’re in that at-risk group … We’ve just started kind of early conversations of those guys in that risk group. … We don’t want to stick them on a plane.”

Dodd’s article notes that most replay officials are retired, former on-field officials. The SEC has been using “collaborative replay” since 2016, which means an on-site official reviews the play in question while an on-site communicator is on the phone with the conference headquarters.

If replays are handled remotely in 2020, one retired referee cautions that calls will have to be made without the full picture.

“There are just so many things they rely on with the naked eye that being remote just won’t allow,” Mike Defee told Dodd via text message. “This will be a real challenge to overcome if they go down that path. I would agree that [replay officials] are generally retired and more vulnerable.”
