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.

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.

McCaffrey finished it off with his run on third-and-short and the 49ers’ defense held on from there, with Dre Greenlaw intercepting Jordan Love for the second time to seal San Francisco’s fifth straight playoff win over Green Bay (10-9).
