Green Bay Packers linebacker Nick Barnett posted on his twitter account today that he has been cleared for at least some contact drills tonight.

Barnett had surgery in mid November to repair a torn ACL and didn’t return to the practice field on a limited basis until last Monday.  This will be his first contact since his knee injury.

Barnett is presumed to be the starter at inside linebacker.  It’s not certain if he’ll play in the team’s third preseason game on Friday night at Arizona.
