Mykel Williams Set for 49ers Debut vs. Seahawks
By Drooid · · How we work
Core Event
San Francisco 49ers head coach Kyle Shanahan announced that defensive end Mykel Williams will be activated from the physically unable-to-perform (PUP) list for the Week 5 matchup against the Seattle Seahawks. Williams suffered a torn ACL and meniscus damage in his right knee, ending his rookie season after nine games.
Background & Context
Williams was the No. 11 overall pick in the 2025 NFL Draft. In his limited rookie action he logged 20 tackles, four tackles for loss, three quarterback hits, one sack and one fumble recovery. The 49ers’ defensive front has been depleted: star pass rusher Nick Bosa is out with a calf injury, defensive tackle James Thompson Jr. is sidelined with an ankle injury, and fullback Kyle Juszczyk is unavailable with a knee issue. Seattle entered the game with Pro Bowl defensive end Leonard Williams cleared to play after an ankle scare, while safety Ty Okada returned from a hamstring injury.
Data & Statistics
- Mykel Williams (2025): 20 tackles, 1 sack in 9 games.
- 49ers record: 4-0; Seahawks record: 3-1.
- Nick Bosa: missed his third straight game (knee, calf).
- Mike Evans: removed from the final injury report, making him eligible for Sunday’s game.
- Seattle’s defense ranks among the league’s best in total yards and passing yards allowed.
Official Statements & Responses
Shanahan said when Williams is on the field he will be “full go” and the staff does not plan to limit his workload. He also described his own calf issue as being at the “junction point” between the gastrocnemius and soleus.

Conflicting Reports & Gaps
The 49ers’ official injury report listed Mykel Williams as “questionable,” while other outlets reported he will be active. No final roster designation was released before kickoff, leaving his exact status ambiguous. Seattle’s report omitted a game status for Leonard Williams, implying availability but not confirming snap count.
What's Next
If Nick Bosa’s recovery proceeds as expected, the 49ers could see him back for the Week 6 home game against Washington. The outcome of the Seattle game will influence the NFC West race, with a 49ers win preserving their unbeaten streak and a Seahawks victory potentially shifting the division lead.
