Arizona Cardinals

Verified Timeline

Lore & Background

The 49ers and Cardinals first met on November 18, 1951 at Kezar Stadium, with the then-Chicago Cardinals winning 27–21 behind Charley Trippi. The Cardinals led the series prior to the arrival of Bill Walsh, Joe Montana, and Jerry Rice. Following the 1987 season, the Cardinals relocated to Phoenix. In the 49ers' first trip to Phoenix, they blundered a 23–0 lead, and the Cardinals came back to win 24–23, scoring a touchdown in the final seconds. During a 1999 game, Cardinals cornerback Aeneas Williams sacked 49ers quarterback Steve Young, who was concussed on the play, an injury that ultimately ended his career. The teams became division rivals when the Cardinals moved to the NFC West as part of the NFL's 2002 realignment. In 2004, the 49ers finished 2–14, but both wins came against the Cardinals. The following season, the teams played the first NFL regular season game outside the U.S. at Estadio Azteca in Mexico City, with the Cardinals winning 31–14. To kick off their 2006 season, the Cardinals hosted the 49ers at the newly opened University of Phoenix Stadium, winning 34–27. From 2007 to 2012, the teams played each other five times on Monday Night Football. In the 2007 matchup, Alex Smith led the 49ers to a comeback victory. The results were lopsided from 2009 to 2013, with the Cardinals winning only one of ten matchups. Then-Cardinals head coach Bruce Arians likened the rivalry to the Browns–Steelers rivalry. From 2015 to 2018, the Cardinals dominated, winning eight straight games. In 2022, the teams met in Mexico for another Monday Night Football matchup, with 49ers quarterback Jimmy Garoppolo passing for 4 touchdowns in a 38–10 victory.

Reader's Guide

The origins of this rivalry stretch back to when the Cardinals were based in Chicago and St. Louis, but it truly ignited upon their relocation to Arizona and placement in the NFC West alongside San Francisco. For decades, the series was characterized by the 49ers' overwhelming dominance during their Super Bowl eras, where the Cardinals often served as a stepping stone rather than a true threat. The biggest clashes have occurred when both teams are fighting for divisional titles or playoff seeding. Notable moments include dramatic late-season games that decided the NFC West champion, often featuring high-stakes fourth-quarter drives and defensive standoffs. The intensity peaked in years where both franchises were ranked among the league's elite, turning every meeting into a potential playoff preview. What makes this rivalry fierce is the divisional necessity; they play twice a year, meaning every point matters for the standings. While the historical record favors San Francisco heavily, the Cardinals' recent resilience has added a layer of unpredictability. The clash of the 49ers' rich championship history against the Cardinals' status as the NFL's oldest franchise creates a unique narrative tension that defines the modern NFC West landscape.
