Post-Laken Tomlinson, the 49ers have prioritized the edges of their offensive line. Trent Williams has stood as a $20MM-per-year blocker since 2021, and the team gave Colton McKivitz another extension after he had replaced top-10 investment Mike McGlinchey at right tackle. That has meant turnover among low-cost players inside. Ben Bartch is part of the latest wave, but he has not made it far in his first season as a full-time San Francisco starter.

Entering the season as the 49ers’ Aaron Banks replacement at left guard, Bartch did not make it out of Week 2. The former Jaguar suffered a high ankle sprain against the Saints, and Kyle Shanahan said he would miss extensive time. That will come to fruition, with the 49ers placing Bartch on IR today, per the San Francisco Chronicle’s Noah Furtado.

This injury is expected to sideline Bartch between four and six weeks, according to NBC Sports Bay Area’s Matt Maiocco. The team will use IR as a result. The 49ers have seven injury activations remaining, having used one of their August IR-return designations on defensive tackle Kevin Givens. While Givens already counts toward that eight-activation total due to a summer designation being used, Bartch will not count toward that number until he is brought back to the 53-man roster.

Tied to a one-year, $1.34MM contract, Bartch beat out Nick Zakelj for the 49ers’ LG job in Week 1. However, seventh-round rookie Connor Colby replaced Bartch when he went down in New Orleans. He will start in Week 3, per The Athletic’s Matt Barrows. Zakelj did not make San Francisco’s 53-man roster but remains on the practice squad. While the young blocker remains an option to provide insurance, the 49ers did not sign him to the active roster in a corresponding move. Tight end Brayden Willis will take Bartch’s place instead.

Colby only arrived as the No. 249 overall pick, but he worked as a four-year starter at Iowa. Blocking for the likes of Kaleb Johnson and Tyler Goodson with the Hawkeyes, Colby earned first-team All-Big Ten acclaim in 2024 and third-team recognition in 2023. Colby made 50 starts at Iowa, providing interesting appeal for a seventh-round pick as a fill-in option. Colby will work opposite 2024 third-round pick Dominick Puni, and it will be worth monitoring if Bartch will return as a starter or a swingman.

A 2020 Jaguars fourth-round pick, Bartch has been in the 49ers’ system since being added shortly after the 2023 trade deadline. Bartch has made 24 career starts, including two last season with the 49ers, but will see his first run as a full-timer since 2022 paused for a while.
