The Kansas City Chiefs defeated the Denver Broncos in spectacular fashion on Sunday by blocking a last-second field goal to seal a two-point victory that keeps their perfect season alive.

In a game where the Broncos seemed to have everything going for them, Kansas City’s defense finally faltered on Denver’s final drive and allowed rookie quarterback Bo Nix to drive into the red zone to set up an easy walk-off field goal for kicker Will Lutz.

With the game hanging in the balance, the Chiefs’ defensive line made a final push and managed to tip Lutz’s kick, which sunk the Broncos’ comeback attempt as time expired.
