49ers vs Cardinals: match preview on 27 September 2026

The 49ers are expected to win this game. The margin between them is not close: three straight victories against five games including four defeats. The home side has outscored opponents 80:32 across its last three matches, while the visitors have conceded 154 points in five outings.

The 49ers have not dropped points in any of their last three games. They opened the season in Melbourne against the Rams, winning 27:7 away from home. Then came 18:12 against the Raiders on the road, and most recently 35:13 over the Dolphins at Levi's Stadium. Against the Dolphins they scored 35 points and limited their opponents to 13, a margin that suggests control rather than luck.

The Cardinals have struggled to find rhythm since their one win over the Chargers. They lost 31:7 at home to the Seahawks, and before that dropped 42:38 away to the Packers in a game where both sides scored freely. The 13:34 defeat to the Cowboys at home and the 30:33 loss to the Panthers complete a difficult run. Their only positive came against the Chargers, where Jakoby Brissett's passing helped secure a 26:14 victory. Since his first start, Brissett has accumulated 3,643 passing yards in 13 games — more than Matthew Stafford, Dak Prescott, and Jared Goff combined over the same period.

The absence of Jake Tonges matters for the 49ers' attack. The tight end suffered an MCL knee injury in the season opener against the Rams and requires surgery, ruling him out for approximately 10 weeks. Deion Stribling is also sidelined for a similar period. Neither absence changes the basic assessment of this match, though it removes one element from San Francisco's offensive options.

A 49ers victory is not guaranteed if the Cardinals adopt a conservative approach and the game stays tight through the first half. The visitors have shown they can score — 26 points against the Chargers, 38 against the Packers — but they have also conceded heavily in several matches. If the match remains within reach for Arizona, the pressure shifts to San Francisco, who have not been tested in this way during their three-game winning streak.

The 49ers' confidence from three consecutive wins, combined with their home advantage and superior point differential, gives them the edge. That will not change unless the Cardinals manage to keep the scoreline close early and exploit any defensive lapses.
