Maligned Packers defensive end Justin Harrell is on a rigorous rehab program at the team's Lambeau Field facilities in the early part of the offseason. Harrell, Green Bay's first-round draft pick in 2007, hasn't played since Dec. 7, 2008. A recurring back injury flared up in training camp last summer, and Harrell missed the entire season. "He is getting close to being fully recovered," head coach Mike McCarthy said shortly after the season ended. "There are definitely some targets that he is going to have to hit throughout the offseason, but he is doing very well in the weight room and the rehab part of it. He is going to be here full time."

I agree with the week 3, though I think it will be week 3 of preseason. (that's if he doesn't hurt himself while taking a shower, eating at the buffet, or trimming his toe nails in the off season)
