The San Francisco 49ers' right guard job was by far the biggest position battle heading into training camp and it looks like Mike Person might be in the lead over Joshua Garnett.

"I would say it's [Person's] job to lose right now, or however you want to say it," head coach Kyle Shanahan said on Tuesday. "Josh could beat him out but Person has been the most consistent since day one and he's had a real good camp. We'll see what happens these last few days."

Garnett will play on Thursday against the Los Angeles Chargers so he still has time to impress the coaching staff. The guard missed much of training camp with a knee injury. He saw his first in-game action during the 49ers' second exhibition game — a matchup against the Houston Texans.

"Josh definitely helped himself out last week, and I'm glad we've got another game to watch it," Shanahan continued. "We had a good practice today. We're still going to evaluate it when we get in there and I look forward to watching him on Thursday."

Shanahan has not yet decided if Person will play on Thursday, which is further evidence that the head coach sees him as the starter at this point.

NFL teams must reduce their rosters from 90 players to 53 by Saturday at 1 p.m. PT. The 49ers kick off the regular season on September 9 against the Minnesota Vikings at U.S. Bank Stadium.
