The San Francisco 49ers have found themselves shuffling their secondary with some regularity in recent weeks. Injuries have been a major issue, with Richard Sherman, Jaquiski Tartt, and Adrian Colbert all missing time due to injuries. Additionally, ineffectiveness at times from Ahkello Witherspoon and Jimmie Ward have resulted in some changes.
This past weekend, the 49ers rotated Greg Mabin into the cornerback position in the second half. He played 29 snaps, and defensive coordinator Robert Saleh said on Thursday that will continue this week.
