Buffalo on New Year's Day, 1967. That victory propelled Kansas City to the first AFL-NFL World Championship Game, later known as the Super Bowl. At the Los Angeles Memorial Coliseum, the Chiefs met Vince Lombardi's powerful Green Bay Packers of the National Football League on January 15, 1967. The Chiefs played the Packers close for a half, trailing 14–10, but Green Bay took control in the final two quarters, winning the game by a score of 35–10. For 1967, the club's special teams got a boost with the addition of kicker Jan Stenerud, and kick returner Noland "Super Gnat" Smith. The Chiefs' first regular season game against an NFL team resulted in a commanding 66–24 Chiefs victory against the Chicago Bears at Municipal Stadium on August 23. Injuries again hit the club hard during the regular season as the Chiefs clawed their way to a 9–5 record. Interest in the team skyrocketed following the team's appearance in the AFL-NFL Championship Game, forcing an increase in seating capacity at Municipal Stadium from 40,000 to 47,000.

The 1968 Chiefs defense allowed a franchise-low 170 points (12.1 ppg). The nucleus of the defensive unit was in its prime, producing six AFL All-Stars, including all three of the squad's linebackers. Offensively, quarterback Len Dawson led the AFL in passing for the fourth time. The Chiefs began the season with a 7–1 record and rattled off five straight victories to close the regular season at 12–2, sharing the AFL Western Conference title with the Oakland Raiders and setting up a one-game playoff between the two teams. Kansas City lost a 41–6 decision at Oakland on December 22 as the Raiders advanced to the 1968 AFL Championship Game against the New York Jets. The loss to Oakland is considered to be the beginning of the Chiefs' rivalry with the Raiders, one of the NFL's most bitter feuds. The Chiefs used the momentum they built during the 1968 campaign by posting a perfect 6–0 record during pre-season play for 1969. The team began the regular season with four consecutive road
