Quarterback Aaron Rodgers was cleared by doctors and returned to practice for the Green Bay Packers on Thursday. Assuming he doesn't have a setback in his recovery from a concussion, he is optimistic he will start Sunday's game against Miami. Rodgers practiced on a limited basis Thursday, taking the majority of snaps during the portion of practice that was open to the media. Packers coach Mike McCarthy said Rodgers completed all the steps in the NFL's protocol to return to the field after a head injury, but the team will monitor his progress before naming him the starter against the Dolphins. http://sports.espn.go.com/nfl/news/story?id=5684910
