Super Bowl LVIII has become a defensive battle.
The Chiefs went three-and-out on their ninth possession of the game, gaining only 8 yards before punting the ball back to the 49ers.
Isiah Pacheco ran for 3 yards, and Patrick Mahomes completed a 5-yard pass to Travis Kelce to set up a third-and-two at the Kansas City 35.
Mahomes was under pressure when he bounced a pass into Richie James, forcing a punt.
The Chiefs have five three-and-outs.
The 49ers, though, muffed the Tommy Townsend punt, giving the Chiefs the ball back at the San Francisco 16.
