49ers Activate Mykel Williams Before Seahawks Matchup

The San Francisco 49ers activated defensive end Mykel Williams for their Sunday matchup against the Seattle Seahawks at Lumen Field, adding defensive depth after his recovery from an ACL tear. According to Niners Wire, the move restores the 2025 first-round pick to the active roster after he missed the start of the 2026 season.

Williams is making his 2026 debut after tearing his ACL in Week 9 of the previous season, according to Niners Wire. The defensive end spent training camp and the first four weeks of the regular season on the physically unable to perform list before returning to the roster.

According to Niners Wire, San Francisco released veteran defensive end Ogbo Okoronkwo on Friday to create space for Williams, then re-signed him and elevated him to the active roster as part of Saturday roster moves.

The 49ers also elevated tight end Jack Stoll ahead of the Seattle game, according to Niners Wire. The move provides additional depth at tight end with fullback Kyle Juszczyk unavailable.

Stoll has appeared in 76 career games during his five-year NFL career, according to Niners Wire. He joins George Kittle, Luke Farrell and Brayden Willis among San Francisco's tight end options for the matchup.

According to Niners Wire, the 49ers and Seahawks were scheduled to begin their game at 1:25 p.m. Pacific Time on Sunday at Lumen Field.
