We talked about it as a staff, and it’s like ‘Why don’t we just wait, maybe play them in Atlanta (next week),” Campbell said. “I think we’ll hold tight and make sure they get plenty of reps out here.”

Coach Jim Harbaugh says the plan is for Trey Lance to start against the Detroit Lions and for DJ Uiagalelei to play in the second half in Canton, Ohio.

On Tuesday, head coach Jim Harbaugh announced that rookies Omarion Hampton, Tre Harris and KeAndre Lambert-Smith will play. Harbaugh also added wide receiver Derius Davis to that list of guys who will play. Harbaugh said Ladd McConkey and Quentin Johnston are the only receivers who won't.
