The San Francisco 49ers produced a thrilling fightback to set up a Super Bowl rematch with the Kansas City Chiefs in Las Vegas.
Defending champions Kansas City won the first of Sunday’s Conference Championship games, beating the Baltimore Ravens 17-10 to reach the NFL’s big game for a fourth time in five years.
The Detroit Lions, one of just four NFL teams never to play in the Super Bowl, then led 24-7 at half-time against five-time winners San Francisco.
But the 49ers scored 17 points in a dramatic eight-minute span to draw level, before going in front for the first time with just under 10 minutes left.
The hosts then held on to win 34-31 and set up a repeat of Super Bowl 54, when Kansas City beat San Francisco 31-20 in Miami.
After winning Super Bowl 57 last year, the Chiefs now have the chance to cement their dynasty by winning a third NFL title in five years and becoming the first back-to-back champions since the New England Patriots in the 2003 and 2004 seasons.
