But head coach Jim Harbaugh reportedly isn’t inclined to bring in other options at the position.
“We got good quarterbacks,” Harbaugh said after the 49ers’ 34-0 home loss to Denver on Sunday, according to Matt Maiocco of CSNBayArea.com.
49ers top reserve quarterback Blaine Gabbert was 8-of-14 for 40 yards against the Broncos, and he was picked once on a long pass down the seam. Overall, Gabbert is 11-of-25 for 60 yards with two interceptions in the preseason. Thompson, the fourth-stringer, has also been picked twice.
Johnson has been the best of the three quarterbacks in exhibition play, completing 8-of-11 passes for 72 yards, but he lost a fumble against Denver.
Any changes the 49ers could make at backup quarterback might not come until teams cut their rosters to 53 players on Saturday, August 30 — two days after San Francisco’s preseason finale at Houston. Last year, the Packers added two reserve passers (Seneca Wallace, Scott Tolzien) after San Francisco released them in late August.
For now, it’s on the 49ers’ backup quarterbacks to show Harbaugh’s faith is well-founded. The backups figure to see their least action of the preseason next Sunday vs. San Diego, but they will be busy at Houston, with starter Colin Kaepernick a candidate to get their entire night off.
