It looks like it'll be at least another week before the Packers have their No. 1 return man, Will Blackmon, available for punts and kickoffs. That means another week of putting starting cornerback Charles Woodson back on punts. After watching their other starting cornerback, Al Harris, injure his elbow while blocking on a punt return, the Packers should be nervous about risking an important player like Woodson on special teams. Blackmon won the return job in training camp thanks to some explosive runs, but he broke his left thumb on Aug. 23. Because he has to wear a bulky cast on his hand, the Packers aren't sure he can catch the ball without the risk of fumbles. Given how they benefited from the Eagles' muffed punts last week, the Packers surely want to wait until they're convinced Blackmon will be sure-handed. Though Blackmon will play on special teams in other capacities, the Packers don't plan to put him back on returns until he can play without a cast or with a smaller wrap. That won't happen until the broken bone is healed, and that hasn't happened yet.
