What happened: The San Francisco 49ers signed 29-year-old offensive lineman Brett Toth to a one-year deal worth a guaranteed $2.215 million, including a $1 million signing bonus. Toth arrives from Philadelphia, where he started four games in 2025 and logged 363 snaps after playing just 224 offensive snaps across his entire prior career. He has lined up at tackle, guard, and center, with two of his 2025 starts coming at center and two at left guard.
Why it matters: San Francisco values experienced interior depth, and Toth's positional flexibility gives the staff a movable piece behind a line still sorting out its rotation. There is no established backup center behind Jake Brendel other than Toth, and his ability to mentor younger linemen like Carver Willis, Connor Colby, and Dominick Puni adds value beyond snaps. His frame limited him on the edge, but his strength lets him hold up inside.
By the numbers: Toth: 6'6", 304 pounds, six accrued seasons. 2025 with Philadelphia: four starts, 363 snaps (two at center, two at left guard) after 224 career offensive snaps entering the year. Contract: one year, $2.215M guaranteed with a $1M signing bonus.
What to watch: Watch how the 49ers slot Toth on the depth chart heading into the 2026 season, particularly whether he settles as the emergency backup to Brendel or pushes for left guard reps. Carver Willis is another candidate at left guard, leaving the interior rotation unsettled.
