The 49ers on Wednesday announced a handful of roster moves as they begin their on-field playoff preparations. Most of the movement came on the practice squad where defensive backs Tayler Hawkins and Jason Verrett were placed on IR. To replace them on the practice roster the 49ers added defensive lineman Sam Okuayinonu and cornerback Terrence Mitchell. San Francisco also opened the practice window for safety and special teams ace George Odum.
