From Tom Silverstein of the Milwaukee Journal Sentinel on Twitter:

#Packers S Sean Richardson (neck) said team doctor has cleared him to resume his career. Said 5 out of 5 doctors agreed it's safe to return. — Tom Silverstein (@TomSilverstein) October 23, 2013

Richardson is not practicing yet and remains on PUP, but said he is more than ready to return and is just waiting for the go-ahead. — Tom Silverstein (@TomSilverstein) October 23, 2013

It's hard to say what's keeping the Packers from allowing Richardson to return to practice, except that they have time on their side. The Green Bay safety had fusion surgery on his neck after his season ended a year ago.

The Packers have a five-week window that opened last week (Oct. 16 being the first day of practice that week) for Richardson to begin practicing.

Once Richardson begins practicing, a separate three-week window opens in which they must either activate him, place him on injured reserve or cut him.

The Packers would have to clear room on their 53-man roster in order to elevate Richardson, should they choose to do so.
