SANTA CLARA, Calif.: The Chicago Bears were two yards from another impossible finish.
They had already survived a wild exchange of touchdowns with the San Francisco 49ers. They had lost the lead with 2:15 remaining. And Caleb Williams had once again moved Chicago down the field with the confidence of a quarterback accustomed to winning games in the final minute.
Four seconds remained Sunday night.
Chicago trailed 42–38.
Williams rolled left, extended the play and threw back across his body toward Jahdae Walker in the end zone.
The pass fell incomplete.
For a Bears team that had repeatedly turned late deficits into victories, the ending was unfamiliar.
San Francisco won 42–38 at Levi's Stadium, ending Chicago's latest comeback attempt just short of another remarkable result.
The game begins with a defensive touchdown
The evening's unusual rhythm began almost immediately.
On San Francisco's first offensive play, linebacker T.J. Edwards intercepted a Brock Purdy pass that had been deflected by Jaylon Johnson.
Edwards returned the interception 34 yards for a touchdown.
Only 15 seconds had elapsed.
Chicago led before its offense had taken the field.
According to Bears historical records, it was the franchise's first interception-return touchdown on an opponent's opening offensive play since at least 1978.
The score should have provided an ideal start.
Instead, it became the opening moment of one of the season's wildest offensive games.
San Francisco repeatedly answered Chicago's scoring.
The teams combined for 80 points, with both quarterbacks demonstrating an ability to exploit defensive openings.
Williams finds his young targets
Williams delivered explosive touchdown passes to two rookies.
Luther Burden III scored on a 35-yard reception late in the first quarter.
Colston Loveland added a 36-yard touchdown.
The plays demonstrated the emerging connection between Chicago's quarterback and its young receiving talent.
Against Burden, Williams recognized the receiver's position relative to safety Ji'Ayir Brown and placed the football over the defender.
The completion required more than arm strength.
It demanded recognition of the coverage and enough touch to deliver the pass into space without allowing the safety an opportunity to recover.
The connection with Loveland supplied another example of how Johnson's offense could generate explosive plays through different personnel.
Williams had now thrown multiple touchdown passes in four consecutive games, the longest such stretch of his young career.
Williams completed 25 of 42 attempts for a season-high 330 yards, two touchdowns and no turnovers, finishing with a 100.3 passer rating. It was his first 300-yard performance of the season after four such games as a rookie. His production came from two distinct scoring designs, rather than repeated throws to one isolated matchup.
On Burden’s touchdown, Johnson’s concept placed Loveland underneath, Moore at an intermediate depth and Burden on the deepest route. Williams chose the receiver who had gained a step beyond the safety. Loveland’s score followed an offside penalty that gave Chicago a free play. Williams rolled right, and the tight end adjusted his route as the quarterback extended the possession. Johnson said the offense had rehearsed the hard cadence that morning, with instructions to attack downfield if San Francisco jumped. The touchdowns showed the rookies contributing through a layered passing design and a practiced response to an opponent’s penalty.
But it was not enough to protect Chicago's lead.
The fourth quarter becomes a race
The Bears moved ahead 38–35 when Cairo Santos connected on a 29-yard field goal with 5:22 remaining.
Chicago needed one defensive stop.
Instead, Purdy found Jauan Jennings for a 38-yard touchdown with 2:15 left.
San Francisco led 42–38.
The pressure shifted back to Williams.
Chicago needed a touchdown.
A field goal would not help.
The Bears began at their own 35-yard line with the clock threatening to end the contest.
Williams extended the drive with a four-yard scramble on third-and-4.
He later found Burden for 14 yards on third-and-10.
Facing fourth-and-5, Williams completed a 13-yard pass to Loveland, moving Chicago to the San Francisco 13 with 26 seconds remaining.
The Bears were still alive.
A lateral, a spike and four seconds
Chicago attempted to manufacture the final yards.
Williams found Loveland over the middle.
The rookie pitched the football to Swift, who moved toward the right sideline.
The 49ers tackled Swift at the two-yard line.
The Bears had no timeouts remaining.
Williams hurried the offense to the line and spiked the ball, preserving four seconds.
Chicago would have one final play.
The opportunity carried obvious similarities to the Bears' previous late-game victories.
Williams had moved his team into scoring position after trailing in the final two minutes.
Now the offense needed one more successful snap.
But Johnson later acknowledged that the Bears did not align in the intended formation.
The disruption affected the final attempt.
Williams scrambled, extended the play and tried to find Walker.
The pass fell incomplete.
San Francisco survived.
The other side of the comeback formula
Chicago's repeated late victories have generated excitement throughout the season.
But Sunday's loss illustrated the danger of requiring extraordinary execution every week.
The Bears had moved into position to score the winning touchdown.
That was an achievement.
Yet they had also surrendered 42 points and repeatedly allowed San Francisco to answer.
An offense can produce 38 points and still lose when the defense cannot consistently generate stops.
Chicago's final possession became a missed opportunity, but it was not the only reason the Bears lost.
San Francisco's offensive production forced Chicago to chase the game again and again.
The Bears needed one final touchdown because their defense had not protected a late three-point advantage.
A difficult loss before January
Chicago fell to 11–5.
The Bears remained positioned for postseason football, but the result created renewed urgency heading into the regular-season finale against Detroit.
The defeat also offered valuable lessons.
Williams demonstrated his ability to direct another high-pressure drive.
Burden and Loveland showed their potential as major offensive contributors.
But Chicago needs to improve defensive execution and avoid the late-game alignment problems that complicated the final snap.
The Bears had spent the season finding ways to win games that appeared lost.
Sunday, they found the other side of that experience.
One incomplete pass separated another celebration from a four-point defeat.
