CBS Sports' No. 2 NFL announcer Ian Eagle will be on call in case anything goes wrong, such as Nantz losing his voice or having a medical emergency. “I’ve actually been the break-glass guy two other times,” he tells The Ringer. Eagle is also the backup for Super Bowl radio announcer Kevin Harlon. As The Ringer's Bryan Curtis notes: "Last year, Fox didn’t need to work up an elaborate emergency plan. Joe Buck was calling the game. In the same press box, Kevin Burkhardt, Fox’s no. 2 announcer, was calling the game on the international feed." But Curtis also points out that NBC doesn't have a backup announcer in case Al Michaels isn't able to call the game. “That thought has never crossed my mind,” said Sunday Night Football executive producer Fred Gaudelli. “It would definitely cross my mind if we were doing this game.” ALSO: NFL won't let the Tampa Bay Buccaneers fire their cannons after touchdowns at their home stadium Sunday.
