Kansas City acquired two Super Bowl MVP's with one fell swoop--Joe Montana from the San Francisco 49ers and Marcus Allen. Allen arrived from Kansas City's most hated rival, the Los Angeles Raiders in a move still talked about today when discussing football's most heated rivalry. Leading into the 1993 season, the Chiefs had not only a proven passer, but also a proven running game to complement their already powerful defense.
The previous season, the Chiefs' starting quarterback was Dave Krieg and their running back was Christian Okoye. Okoye suffered a knee injury prior to training camp in 1993, but keeping Krieg would prove to be a wise decision in the event of injury to the new starter Montana.
Chiefs kicker Nick Lowery made the winning 32-yard field goal after 11:03 of overtime. The Steelers scored first on tight end Adrian Cooper's 10-yard touchdown reception from quarterback Neil O'Donnell. Kansas City then tied the game after backup quarterback Dave Krieg, who temporarily replaced injured starter Joe Montana, threw a 23-yard touchdown to wide receiver J.J. Birden. However, Pittsburgh scored 10 unanswered points in the second quarter: kicker Gary Anderson's 30-yard field goal and O'Donnell's 26-yard touchdown completion to wide receiver Ernie Mills. After Lowery made a 23-yard field goal in the third quarter, the Chiefs eventually tied the game in the fourth period with running back Marcus Allen's 2-yard touchdown. However, the Steelers marched 74-yards to take the lead on O'Donnell's third touchdown pass of the game, a 22-yard score to tight end Eric Green. In the final minutes of regulation, Keith Cash blocked a Pittsburgh punt and Fred Jones returned it to the Steelers 9-yard line. On fourth down, wide receiver Tim Barnett scored on a 7-yard touchdown reception from Montana to tie the game. Then after forcing Pittsburgh to punt, Kansas City drove 47 yards to set up Lowery's 43-yard field-goal attempt in the closing seconds, but the kick was wide right and thus the game went into overtime. Montana finished the game with 276 passing yards and a touchdown, with no interceptions.
Chiefs quarterback Joe Montana threw three touchdown passes in the second half to give his team a 28–20 win. The Oilers jumped to a 10–0 lead in the first quarter with kicker Al Del Greco's 49-yard field goal and running back Gary Brown's 2-yard touchdown. Then after a scoreless second period, Montana threw a 7-yard touchdown pass to tight end Keith Cash in the third quarter. In the fourth period, Del Greco kicked a 43-yard field goal to give Houston a 13–7 lead. But aided by a 38-yard pass interference penalty, the Chiefs advanced 71 yards to score on wide receiver J.J. Birden's 11-yard touchdown reception form Montana. On the Oilers' next possession, Kansas City defensive lineman Dan Saleaumua recovered a fumble by Houston quarterback Warren Moon, setting up Montana's 18-yard touchdown pass to wide receiver Willie Davis. The Oilers then drove 80 yards to score on wide receiver Ernest Givins' 7-yard touchdown catch, but the Chiefs responded with running back Marcus Allen's game-clinching 21-yard touchdown run that capped off a 79-yard drive. The Oilers had 1:51 left to score but failed on a 4th down attempt on their own 20 yard line. The Chiefs have not won a playoff game since this game.
Running back Thurman Thomas led the Bills to the 30–13 victory by recording 186 rushing yards, 3 receptions for 22 yards, and three touchdowns. Buffalo scored first on Thomas' 12-yard touchdown run before Chiefs kicker Nick Lowery kicked two field goals. In the second quarter, Thomas scored on a 3-yard touchdown and Bills kicker Steve Christie made two field goals to extend the lead 20–6. With 21 seconds left in the first half, the Chiefs reached the Buffalo 5-yard line, but quarterback Joe Montana's pass was intercepted by Bills defensive back Henry Jones. Montana later suffered a concussion during the third play of the third quarter and left the game. Kansas City backup quarterback Dave Krieg then led his team on a 90-yard drive to score on running back Marcus Allen's 1-yard touchdown. However, Buffalo scored 10 unanswered points in the final period, an 18-yard field goal by Christie and a 3-yard touchdown by Thomas, to preserve the victory
^For the 1993 NFL season, all teams were scheduled two bye-weeks over the newly expanded 18-week schedule. This was the only time in NFL history that the season expanded to 18-weeks with 16 games. The format changed for the 1994 season.
