Pettis reunites with the 49ers, who add him for receiver depth given the rash of pass-catcher injuries to open the season. He began his career as a second-round pick for San Francisco, bouncing around as a depth receiver and special teamer with the Giants, Bears, and Saints as well. Pettis may see some game day action soon given his familiarity with Kyle Shanahan, but he should be nowhere near fantasy rosters.
