Packers quarterback Aaron Rodgers (collarbone) went through individual drills Tuesday, but his chances to play Thursday at Detroit (Week 13) remain slim.

"It was a good day for throwing and he feels good, but I don't feel he's going to make it this week," Packers coach Mike McCarthy said of Rodgers. "Chances are closer to none that he will play. This is a medical decision, and he's not quite ready."

McCarthy still didn't name a starting quarterback for Thursday's game. Matt Flynn took the first-team reps, but McCarthy reiterated he is getting Scott Tolzien ready for Week 13 as well.
