The 49ers schedule brings a crucial NFC West test on Sunday, October 11, 2026, with San Francisco facing the Seattle Seahawks at Lumen Field. The 49ers have finalized their inactive list, and the announcement includes both a major absence and an encouraging defensive return.
San Francisco entered Week 5 with a perfect 4-0 record, but the team will have to manage several unavailable players in a challenging road environment. Defensive lineman Nick Bosa is among the seven inactives, while Mykel Williams and Upton Stout are active after entering the weekend listed as questionable.
Breaking 49ers Schedule Update: Bosa Ruled Out
Bosa was ruled out on Friday’s final injury report because of knee and calf issues. His absence creates an immediate challenge for a 49ers defense preparing to face Seattle’s offense in a divisional matchup.
The star defensive lineman has been a central part of San Francisco’s pass rush and defensive leadership. Without him available, the 49ers will rely more heavily on their remaining defensive front to generate pressure, control the line of scrimmage and limit Seattle’s ability to extend drives.
James Thompson Jr. is also inactive with an ankle injury. The two defensive line absences could lead to increased responsibilities for the players available up front, particularly in early downs and obvious passing situations.
Mykel Williams Finally Makes His Season Debut
The biggest positive development for San Francisco is the return of Mykel Williams. The defensive lineman began the season on the reserve/PUP list while recovering from an ACL injury suffered during Week 9 of the 2025 season.
Williams returned to full participation in Friday’s practice and was elevated to the active roster before the Seahawks game. His activation gives the 49ers another powerful option along the defensive line and could provide a significant boost despite Bosa’s absence.
Because Sunday marks Williams’ season debut, his workload and effectiveness will be closely watched. Even if he is eased into action, his presence adds depth, athleticism and another potential source of disruption for Seattle’s offense.
Critical Inactives for San Francisco
The complete list of 49ers inactives for Week 5 against Seattle includes:
- DL James Thompson Jr.
- LB Tatum Bethune
- DL Nick Bosa
- OL Enrique Cruz Jr.
- QB Kurtis Rourke
- FB Kyle Juszczyk
- S Marques Sigle
Fullback Kyle Juszczyk will also miss the game because of a knee injury. His absence could affect San Francisco’s offensive formations, short-yardage packages and blocking versatility. Juszczyk has long been valued for his ability to contribute as both a lead blocker and a dependable receiving option.
Safety Marques Sigle is inactive with an ankle injury, while linebacker Tatum Bethune, offensive lineman Enrique Cruz Jr. and quarterback Kurtis Rourke are also sidelined. The inactive list reflects the usual game-day roster limitations, with only 48 players eligible to participate.
Upton Stout Cleared for the Seahawks Matchup
Cornerback Upton Stout was listed as questionable because of a shoulder issue but is active for Sunday’s contest. His availability is especially important against a Seattle team capable of testing the secondary with speed, spacing and play-action concepts.
Stout’s return helps preserve San Francisco’s options in the defensive backfield. With Sigle unavailable, having another healthy defensive contributor available should provide valuable flexibility for the coaching staff throughout the game.
Why This Week 5 Game Matters
The 49ers schedule has placed San Francisco in a demanding divisional environment just five games into the season. The team’s 4-0 start provides momentum, but a road meeting with Seattle can quickly alter the NFC West picture.
Seattle’s Lumen Field is known for its intense crowd noise, making communication and discipline essential for the visiting 49ers. The offense will need to remain efficient, while the defense must avoid giving up explosive plays or allowing Seattle to control possession.
San Francisco’s ability to overcome Bosa’s absence may be one of the defining storylines. Williams’ return offers hope that the defensive line can maintain pressure, but the unit will need contributions from multiple players to replace the production of its injured star.
For fans tracking the 49ers schedule, Sunday’s matchup is more than another regular-season game. It is an early test of roster depth, defensive resilience and the team’s ability to protect its unbeaten record against a familiar NFC West rival.
