4-0 49ers Face Seahawks Test

The 4-0 San Francisco 49ers have opened the 2026 season strongly, but coach Kyle Shanahan says he is focused on the next game, warning that past teams’ hot starts have not guaranteed sustained success. San Francisco’s offensive line has yet to allow a sack, while the team has also shown it can remain effective when star pass rusher Nick Bosa is sidelined, with Fred Warner continuing to anchor the defense. The 49ers now face a major test against Seattle, whose disciplined, aggressive defense has held San Francisco to just nine combined points in their last two meetings. Shanahan praised offensive line coach Chris Foerster’s ability to develop players, while stressing that the team still must identify the right prospects rather than simply favoring later-round picks. Shanahan also became the 49ers’ longest-tenured head coach, surpassing Bill Walsh, and George Kittle credited his consistent standards and preparation with helping shape the team’s culture.
