SANTA CLARA, Calif. — 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 beat the Green Bay Packers 24-21 in a divisional-round playoff game on Saturday night.

After spending all 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.

Purdy went 6 for 7 for 47 yards on the decisive drive, converting a third down to Brandon Aiyuk and then a 17-yarder to Chris Conley.

Ravens 34, Texans 10

BALTIMORE — Lamar Jackson threw two touchdown passes and ran for two scores, and Baltimore beat Houston to advance to the AFC title game.

Jackson helped the Ravens (14-4) take control in the third quarter after the teams entered the half tied at 10. His 15-yard scoring run put Baltimore ahead to stay, and he connected with Isaiah Likely from 15 yards to make it 24-10.
