The 49ers also won’t have left guard Aaron Banks and left tackle Jaylon Moore the last two games, Shanahan said. Banks has a medial collateral ligament injury in his knee and Moore has a quad strain. Guard Spencer Burford (calf) underwent an MRI on Monday to determine the severity of his injury.

The 49ers finished the Miami game with Spencer Buford, the No. 3 tackle, replacing Moore and Nick Zakelj filling in for Banks. And Burford is no sure thing to face Detroit when the 49ers host the Lions in Week 17 on Monday night.

One day after his team was eliminated from postseason contention, 49ers coach Kyle Shanahan announced that left tackle Trent Williams, left guard Aaron Banks and backup tackle Jaylon Moore will miss the team's final two games.

San Francisco 49ers offensive linemen Trent Williams, Jaylon Moore and Aaron Banks won't play the rest of the 2024 NFL season due to injury.

The San Francisco 49ers have been without All-Pro left tackle Trent Williams for the last five games, and the future Hall of Famer will also miss the final two. Niners head coach Kyle Shanahan confirmed in his Monday conference call with local media that the 11-time Pro Bowler will not feature against the Detroit Lions or the Arizona Cardinals because of the ankle injury that has kept him out since the Week 11 loss to the Seattle Seahawks.
