San Francisco's comeback win over the host Falcons in the 2012 NFC championship game sealed their trip to the Super Bowl. Atlanta got a taste of revenge a few years later on their own Super Bowl run behind an offense designed by current 49ers coach Kyle Shanahan.

The San Francisco 49ers look to ground the high-flying Atlanta Falcons on "Sunday Night Football."

The Falcons are coming off a 24-14 win over the Buffalo Bills last week.
