49ers head coach Kyle Shanahan provided injury updates Friday afternoon on a conference call after Thursday’s preseason finale. Defensive tackle Akeem Spence is in the concussion protocol. Linebacker Curtis Robinson has a high-ankle sprain. Linebacker Oren Burks suffered a knee sprain, but he’s expected to return in Week 1.
Shanahan said Thursday’s game wasn’t as bad as it felt, but only because it couldn’t have felt worse. He ended his opening comments by saying, “We have to clean that stuff up and make some decisions this week to help it.” That came off as someone who isn’t going to tolerate penalties or sloppy play any longer.
