After losing starting offensive linemen Aaron Banks and Jaylon Moore, the 49ers are counting on certain backups to step up this year. Unfortunately for the 49ers, they just announced that they’ve placed projected starting left guard Ben Bartch on the Non-Football Injury List today. For all we know, the 49ers will activate Bartch to the 90-man active roster tomorrow — they can activate him at any time. Last year, he started two games for the 49ers at left guard.
