Brock Purdy threw for 267 yards and a touchdown, and the San Francisco 49ers rallied from 17 points down at halftime to beat the Detroit Lions 34-31 and reach the Super Bowl. The 49ers scored 17 points in an eight-minute span of the third quarter to tie the game and then pulled away in the fourth quarter to earn a rematch against Kansas City after losing to the Chiefs in the Super Bowl four years ago. Detroit became the fourth team to lose a conference title game after leading by at least 17 points and was unable to make the Super Bowl for the first time in franchise history.

Patrick Mahomes and Travis Kelce were at their magnificent best in the first half, and Kansas City’s defense delivered another masterpiece against Lamar Jackson and Baltimore, helping the Chiefs reach the Super Bowl for the fourth time in five years with a 17-10 victory in the AFC championship game. Kelce caught 11 passes for 116 yards and a touchdown with girlfriend Taylor Swift again in attendance. Kansas City will face San Francisco in Detroit on Feb. 11, seeking to become the first team since New England 19 years ago to win it all in back-to-back seasons.
