The retired three-time Super Bowl MVP quarterback will join the network's crew for daylong coverage of Sunday's NFL championship game between the Baltimore Ravens and San Francisco 49ers.
Favre hasn't been heard from much since retiring after the 2010 season. He returns to the city where he led the Green Bay Packers to a 35-21 win over New England in the 1997 Super Bowl.
Favre said in an email to The Associated Press that he doesn't miss the "grind and stress of day-to-day football, but I do miss my teammates and coaches."
He also said it will "be great to reconnect with NFL fans around the Super Bowl."
Favre will join host Rich Eisen and several Super Bowl-winning players, including Marshall Faulk, Kurt Warner and Deion Sanders.
