The San Francisco 49ers closed out the regular season with a frustrating 13–3 loss to the Seattle Seahawks on Saturday night at Levi’s Stadium. This game was defined almost entirely by defense, field position, and missed opportunities.
Playing without left tackle Trent Williams and wide receiver Ricky Pearsall, the 49ers took the field in blackout uniforms for the rivalry finale, but windy conditions in Santa Clara and a relentless Seahawks defense made offense hard to come by all night. The loss drops San Francisco into the No. 5 or No. 6 seed, depending on the result of Sunday’s Arizona Cardinals at the Los Angeles Rams matchup, while Seattle locked itself into the No. 1 seed.
Seattle received the opening kickoff and immediately set an odd tone for the game. Despite being the league’s most conservative fourth down team entering Week 18, the Seahawks went for it on fourth-and-goal on their first drive and came away with nothing. The 49ers defense held firm, setting the stage for what would become a defensive slugfest.
Unfortunately for San Francisco, the offense couldn’t capitalize. The 49ers went three-and-out on their opening possession and struggled throughout the first quarter. Brock Purdy faced constant pressure, rarely finding time to set his feet, while Christian McCaffrey was bottled up early, finishing the first half with just three carries for seven yards.
Seattle broke the scoreless tie on its second drive when Zach Charbonnet punched in a touchdown, aided by a missed tackle from safety Malik Mustapha. From there, points were at a premium. Seahawks kicker Jason Myers, who had made 18 straight field goals entering the game, missed from 47 yards, while San Francisco’s defense continued to bend without breaking.
The 49ers defense was flying early. Renardo Green returned after missing two games with a neck injury, and linebacker Tatum Bethune recorded his first sack of the season midway through the opening quarter. Still, offensive support never arrived. San Francisco failed on a fourth-and-one attempt midway through the second quarter, and at that point Seattle had allowed just one first down all game.
Injuries added to the frustration. Dee Winters and Jauan Jennings both visited the medical tent in the first half, while Bethune later exited in the third quarter and briefly returned before leaving again.
Myers redeemed himself with a 45-yard field goal late in the first half, but Eddy Piñeiro responded by banking in a 49-yard kick just before halftime. Despite everything, the 49ers trailed only 10–3 at the break.
The second half followed the same script. The 49ers received the kickoff, but Brian Robinson fumbled on the return and barely recovered. Defense dominated the third quarter, with neither team scoring and San Francisco’s unit continuing to stack stops despite being on the field far too long.
Seattle extended the lead early in the fourth with a 31-yard field goal which was set up only because Kenneth Walker III converted a critical third-and-17. The 49ers finally mounted a promising red-zone drive later in the quarter, but it ended disastrously when a Purdy pass was tipped by McCaffrey, bobbled, and intercepted by Drake Thomas.
Myers later hit the upright on another attempt, but the damage was already done. Seattle ran out the clock behind a suffocating defensive performance, holding San Francisco to just 173 total yards.
The loss spoiled the regular-season finale, but it also showcased something important: the 49ers defense can very much be real. They simply played too many snaps. Seahawks head coach Mike Macdonald, the second-youngest coach in the NFL, improved his road record to an absurd 15–2.
For San Francisco, the focus now shifts to getting healthy and gearing up for their first wildcard game. The offense never found rhythm, but the defense proved it can go toe-to-toe with anyone. With the playoffs ahead, the priority is clear: recover, reset, and be ready when it matters most if they want any shot at the Super Bowl.
