SANTA CLARA –- The 49ers started the same group of offensive linemen for the first two exhibition games, but coach Jim Tomsula said that is not an indication the competition is over.
“No, it’s not the unit we’ve settled on,” Tomsula said Monday, one day after the 49ers’ 23-6 victory over the Dallas Cowboys in the second exhibition game for both teams.
“We are not settled there. We’re getting closer. But you saw some guys, as we played there with the first two groups -- even the third group."
The left side of the offensive line is set with tackle Joe Staley and guard Alex Boone. Veteran Erik Pears appears to be unchallenged at right tackle. But center Joe Looney and right guard Marcus Martin have yet to officially nail down their jobs.
“I like what Looney did,” Tomsula said. “I like where we’re going with Marcus. He’s really doing a nice job, in terms of every week getting better at the guard position. . . I like where those guys are going. But I don’t want to tell anybody we’re settled.”
The 49ers are likely to take a longer look at recently acquired right guard Jordan Devey, who started four games last season with the New England Patriots. The 49ers acquired Devey last week in a trade that sent tight end Asante Cleveland to New England.
Devey played 23 snaps at right guard with the third-team offensive line on Sunday night. Rookie Ian Silberman played 25 snaps at right guard with the second unit. Dillon Farrell played 48 snaps at center.
“I thought he did very well,” Tomsula said. “I would expect you to see him playing a little earlier. I liked what Ian did at the right guard spot during his time, also. We got Marcus Martin. I like what he did. And (we’re) working Brandon (Thomas) over on the left side. That was getting some live work there in that situation. He did some nice things.”
Thomas worked at left guard with the third-team offense after seeing considerable action a week earlier at right guard with the second team. Tomsula said the 49ers moved Thomas back to his more-familiar left side after showing improvement physically after returning to action from missing last season with a torn right ACL.
“As we were getting him through the process, (we) noticed there was a hitch in his giddy-up on his third step,” Tomsula said. “So we put him on the right to get that hitch out of the giddy-up. It worked really well. We’ve seen him completely moving great, so we wanted to put him back to the left and see how comfortable he was, and it was very good.”
Center Daniel Kilgore, who opened last season as the starter, is likely to miss the first part of the season as he continues to rehab from follow-up surgery in June on the fractured left lower leg that sidelined him in October.
