The Kansas City Chiefs, who for most of this regular season looked more vulnerable than at any time since Patrick Mahomes became their starting quarterback in 2018, are going back to the Super Bowl.

The Chiefs scored a touchdown on each of their first two possessions and then held on to beat the Baltimore Ravens 17-10, sending Kansas City to the Super Bowl for the fourth time in the past five years.

As the seconds ticked away in the San Francisco 49ers' Super Bowl LIV loss to the Kansas City Chiefs, tight end George Kittle was filmed on the sideline vowing to return to the NFL's biggest stage. It took four years and a historic Sunday comeback -- but the Niners finally made good on Kittle's promise.

With their stunning 34-31 come-from-behind win against the Detroit Lions in Sunday's NFC Championship Game, the 49ers are not only returning to the Super Bowl but will get a chance to avenge that loss to the Chiefs on Feb. 11 at Allegiant Stadium in Las Vegas.

Christian McCaffrey scored his second touchdown on a 6-yard run with 1:07 to play, and the San Francisco 49ers mounted their first second-half comeback of the season to defeat the Green Bay Packers 24-21 in a divisional round playoff game on Saturday night.

After spending the regular season as front-runners, the Niners (13-5) needed to come from behind for a change, and Brock Purdy and McCaffrey did just enough on the last drive to send San Francisco to its third straight NFC Championship Game. The Niners will host the winner of Sunday's game between Tampa Bay and Detroit next weekend for a spot in the Super Bowl.

Lamar Jackson threw two touchdown passes and ran for two scores, and the Baltimore Ravens pulled away in the second half for a 34-10 win over the Houston Texans on Saturday to advance to the AFC championship game.

On one of his most productive rushing days of the season, Jackson helped the Ravens (14-4) take control in the third quarter after the teams entered the half tied at 10.
