The Packers also revealed that new starting center J.C. Tretter, who missed most of his rookie season with an ankle injury, has what coach Mike McCarthy termed a "significant" knee injury, and will miss multiple weeks. He will be replaced in the starting line-up by rookie Corey Linsley.
Defensive tackle B.J. Raji sustained a biceps injury in the Friday night contest against the Oakland Raiders and some media reports say he will require surgery and be out for the year. McCarthy would not confirm the surgery, but said Raji would not be a candidate for the in-season injured reserve.
