Aaron Rodgers is officially back, and the Packers are confident enough that he’s healthy that they’re only keeping two quarterbacks on the roster. The Packers have activated Rodgers off injured reserve, clearing the way for him to start tomorrow. Green Bay also released backup quarterback Joe Callahan, meaning the Packers only have two quarterbacks, Rodgers and Brett Hundley. If Callahan clears waivers, he could be re-signed to the practice squad next week.
