Niners head to halftime leading Chiefs in Super Bowl LVIII
Niners' rookie kicker Jake Moody opened the scoring for the 49ers by booting a Super Bowl record-setting 55-yard field goal in the opening moments of the second quarter.
The Niners extended their lead when receiver Jauan Jennings hauled in a short pass from Purdy and threw it back across the field to Christian McCaffrey, who followed his blocks and broke free for a touchdown, putting San Francisco up 10-0.
Chiefs kicker Harrison Butker netted the Chiefs' first points of the game with his 28-yard field goal.
Niners quarterback Brock Purdy has thrown for 123 yards on 10 completions.
