The head coach also provided several other injury updates.
Cornerback Richard Sherman will miss some time with a hamstring strain, which was first reported on Monday morning by Tom Pelissero of NFL Network.
"It will probably be a couple of weeks," Shanahan said of Sherman's status.
Defensive end Dee Ford will also be out a few weeks with a hamstring injury.
"He re-aggravated the same one, so it's going to probably take a little bit longer than it did last time," Shanahan said. "It will probably be at least three weeks."
