The San Francisco 49ers produced a nerve-wracking fightback in the NFL play-offs to survive a scare against the Green Bay Packers.

The 49ers are the favourites to win Super Bowl 58 and hosted the Packers, the seventh and lowest seed in the NFC Conference, in the divisional round.

The Packers trailed 7-6 after a tense first half but led 21-14 following a thrilling third quarter and were still in front as the hosts regained possession with just over six minutes remaining.

But quarterback Brock Purdy led a game-winning drive which put San Francisco within one win of the NFL’s championship game.
