49ERS SQUAD SHOW: KEY TRAINING CAMP BATTLES Continue, INJURIES Stacking Up

Several defensive players have really stood out throughout camp, but perhaps the biggest surprise has been rookie Romello Height, who has showcased explosive speed and pass-rush ability off the edge. Injuries keep stacking up as the electrical substation appears to be in mid-season form.
