Hargrave (concussion/knee) is active for Thursday Night Football against the Falcons, Mike Spofford of the Packers' official site reports.
The defensive tackle entered the day with a questionable tag after practicing on a limited basis during the week leading up to the game. Hargrave had to be cleared by an independent neurologist for full contact to have a chance to play Thursday night, and it appears that he has gotten that clearance. The veteran should be ready to start at nose tackle.
