Dominick Puni’s knee rehab is trending positively and he could be ready for Week 1, per Kyle Shanahan. Ben Bartch has returned to practice, raising the 49ers’ interior guard depth, while Connor Colby would step in at right guard if Puni can’t play. SF opens at Seattle, making interior blocking and Purdy’s protection pivotal to early success.

Bartch’s return bolsters run and pass protection on the right side; Colby’s preseason work gives San Francisco confidence in Week 1 depth. The trio—Puni, Bartch, Colby—shapes the 49ers’ Week 1 plan against Seattle and sets the tone for interior stability all season.
