SANTA CLARA -- Even during the 49ers' bye week, the club made what has become an expected weekly move.
The 49ers have found a way to, essentially, keep 54 players on their 53-man roster with the re-signing of veteran quarterback Josh Johnson. Special teams player Bubba Ventrone was released, again, to make room on the roster for Johnson.
The 49ers re-signed Johnson for the third time since Sept. 23 so that he will be available to practice next week when the 49ers return from the bye week.
Coach Jim Harbaugh said recently that Johnson and Blaine Gabbert are "neck and neck" for the team's backup job behind Colin Kaepernick.
Gabbert has served as the No. 2 quarterback for every game this season. Gabbert made his 49ers debut on Sunday in mop-up duty late in a 42-17 loss to the Denver Broncos.
He completed 3 of 7 pass attempts for 38 yards, including a 20-yard touchdown pass to rookie Bruce Ellington.
The 49ers can be expected to release Johnson and re-sign Ventrone at some point shortly before their Nov. 2 game against the St. Louis Rams.
