SANTA CLARA – What you see is not necessarily what you get once training camp comes to an end.

Yes, undrafted rookie guard/center Erik Magnuson was seen on video posted on the 49ers official website working with the 49ers’ first-team offensive line. But, according to Kyle Shanahan, it was not exactly the 49ers’ first-team offensive line.

The 49ers practiced this week as if they were getting ready for a regular-season game. During the season, the second-team offense does not take the field together to run plays. The starting unit might feature a backup at a position or two to give starters a break.

“Just because you see guys in a picture that might be in and there’s ones next to him, that doesn’t mean he’s going with the ones,” 49ers coach Kyle Shanahan said. “It means whoever was there just got a break that play. There’s plenty of times you might, if you looked at practice this week, you’d see the starting O-Line in there and C.J. (Beathard) would be at quarterback, because we don’t want Brian (Hoyer) to go 10 plays in a row and he took a run play off or something like that.”

Shanahan said there has been no change to the 49ers’ first-team offensive line, which has featured tackles Joe Staley and Trent Brown, guards Brandon Fusco and Zane Beadles, and center Daniel Kilgore.
