Some notes from 49ers camp on Tuesday:
Smith apparently suffered the injury while making a 5-yard catch in Saturday’s exhibition loss at Denver. He showed no hindrance at practice, nor while seen walking around in the locker room.

Kendall Hunter looked to be favoring his reconstructed right knee while working on a side field with a trainer at the start of practice. Hunter had seven carries for 15 yards Saturday in his first game action since the 2013 season finale.
