Green Bay Packers receiver Robert Ferguson re-injured his left knee Friday and was carted off the field just one day after returning to practice. Ferguson missed the last three games after tearing a ligament in the knee during a 23-20 loss at Minnesota on Oct. 23. He is expected to be evaluated further on Saturday, team spokesman Aaron Popkey said late Friday afternoon. Coach Mike Sherman wasn't made available to reporters Friday. He is expected to update Ferguson's status during his scheduled news conference Saturday after practice. "It's just bad luck. There's nothing we can do about it," receiver Donald Driver said of the spate of injuries to Green Bay's offensive players this season. "How do you get good luck? Do you need to do something, give somebody a gift or something? I don't know. But, right now, it just seems like it's not going our way."
