Pete Dougherty, of the Green Bay Press-Gazette, reports Green Bay Packers LB Nick Barnett (knee) expressed disappointment on his Twitter page that he failed his pre-training camp physical. Barnett wrote, "I'll be back. This is just a small delay." Head coach Mike McCarthy said, "I couldn't tell you (when Barnett will back). It's just really on how he tests. It's just a normal process. Nick has been working exclusively with the trainers (all offseason). Now it's time for Nick Barnett and (inside linebackers coach) Winston Moss to get more into the football drills with the coach as opposed to the trainer, because it goes to a different level (in training camp). He just has to take that next step." LB Brandon Chillar or LB Desmond Bishop will work with No. 1 defense while Barnett is out. Source: FootballGuys.com
