Cowboys fullback Deon Anderson will be out 2 to 4 weeks after left knee surgery.
Anderson underwent the procedure Thursday to repair a torn meniscus. While Dallas has another fullback in rookie Chris Gronkowski, coach Wade Phillips said it's possible they will add another fullback or tight end.
Also Thursday, linebacker DeMarcus Ware returned to practice on a limited basis as he recovers from a slight concussion. He's expected to participate fully on Friday.
