If you see Randy Moss wearing sunglasses on ESPN’s Sunday NFL Countdown, there’s a reason for that choice.

The Hall of Fame receiver-turned-analyst opened Sunday’s broadcast by explaining that he was wearing blue-tinted glasses because he and his family were “struggling with something internally.” Moss made it clear he would be fine.

In a video posted to Instagram before the show, Moss said that the “internal” issue had already existed for the past week and that he would be wearing glasses throughout the show.

“Throughout the holiday week, your boy was struggling with something internal,” Moss said. “I have a great medical team and a great family around me.”

In the video, Moss added that ESPN insider Adam Schefter called the blue-tinted sunglasses “Michigan turnover glasses” – an apt joke after Michigan’s win over Ohio State on Saturday.

Moss did not provide further details about the illness or cause behind the glasses, but urged people to check with their doctors. “Do all your checkups, do your blood work, and we’ll take care of it,” he said.

Moss has been an analyst on “Sunday NFL Countdown” since 2016 and is the show’s longest-serving panelist.
