In addition, the 49ers have signed offensive lineman Brandon Parker to the practice squad. He was one of five offensive linemen who worked out for the team on Tuesday.
Bartch suffered a high-ankle sprain in the 49ers' Week 2 win over the New Orleans Saints and will be out for at least the next four games. Rookie Connor Colby will likely start in his place at left guard.
The 49ers Communications staff provided the following rundown.
Willis (6-4, 240) signed to the team's practice squad on August 27, 2025, and has appeared in one game with the team this season. Bartch (6-6, 315) started each of the team's first two games this season.
Parker (6-8, 320) was originally drafted by the Oakland Raiders in the third round (65th overall) of the 2018 NFL Draft. Throughout his six-year career with the Raiders (2018-23), 49ers (2024), and Atlanta Falcons (2024-25), he has appeared in 59 games (33 starts) and started in one postseason contest. In 2024, Parker spent time with both the 49ers and Falcons. He signed to the Falcons practice squad on August 27, 2025, and was later released by the team on September 2.
A 29-year-old native of Kannapolis, NC, Parker attended North Carolina Agricultural and Technical State University for five seasons (2013-17), where he started in 48 games. Parker was named the MEAC Offensive Lineman of the Year in consecutive seasons (2015-16) and was a three-time All-MEAC selection (2015-17).
