The Detroit Lions dominated the ball and the scoreboard in a stunning first half in San Francisco.
They won the line of scrimmage on both sides of the ball while rumbling to 148 first-half rushing yards against a strong 49ers defensive front en route to a 24-7 halftime lead. Can the they keep it up to make it two upsets of No. 1 seeds in two games on Sunday? Or will the 49ers mount a rally in the second half?
The winner gets the Kansas City Chiefs in the Super Bowl.
