What happened: The San Francisco 49ers added 29-year-old offensive lineman Brett Toth on a one-year deal to bolster their interior depth heading into the 2026 season. Toth started four games for the Philadelphia Eagles in 2025, logging 363 snaps after taking just 224 across his prior career. He has lined up at tackle, guard and center, with two of last season's starts coming at center and two at left guard.

Why it matters: San Francisco has no established backup center behind Jake Brendel, making Toth's positional flexibility valuable as the line sorts out its depth chart. His most likely role is emergency interior fill-in rather than a locked-in starter, and where he settles will hinge on how the competition at left guard shakes out. The signing also gives the 49ers a veteran voice for younger linemen.

What to watch: Watch whether Toth wins the primary backup center job behind Brendel or competes at left guard, where Carver Willis is also in the mix. Training camp reps should clarify his spot on the depth chart alongside young linemen Connor Colby and Dominick Puni.
