SANTA CLARA -- Three members of the 49ers’ starting offensive line were held out of practice Wednesday because of knee injuries.
Left tackle Joe Staley, right tackle Mike McGlinchey and center Weston Richburg, each of whom sustained a knee injury Sunday in the 49ers' loss to the Los Angeles Chargers, didn't practice as the team began preparations to face the Arizona Cardinals this week.
Each of the linemen, along with wide receiver Marquise Goodwin, is questionable for Sunday’s game. Goodwin is battling injuries to his hamstring and thigh.

Rookie receiver Dante Pettis also didn't practice, and has been ruled out with a knee injury.
“I know the fortunate thing is, not counting our quarterback (Jimmy Garoppolo) and our running back (Jerick McKinnon), all of the O-Linemen and the receivers I spoke about today, they’re not going on IR,” 49ers coach Kyle Shanahan said. “They will return eventually, hopefully sooner than later.”
Cornerback Richard Sherman didn't practice because of a calf strain and appears to be doubtful to play against the Cardinals. Sherman sustained the injury Sept. 23 in Kansas City and didn't play last week against the Chargers.
Another of the 49ers' starting offensive linemen, right guard Mike Person, was limited with a knee injury. Running back Matt Breida (shoulder) also was limited.
