Pennel and Goodson will be coming of their suspensions after the next game. It's likely that Price or Ringo will be released to make room for Pennel. I'm not so sure there will be a spot for Goodson.
Obviously, there are a number of rookie DBs, any one of which could be released to make room for Goodson, but I'm not sure the Packers will want to do that. They already have 11 DBs, so I can't see them creating a spot for another by releasing someone at a different position.
I have always thought Goodson's suspension might lead to his release, because others would show they were just as good, but younger and with more years of roster control. While I originally thought Robertson Daniel might be one to do so, he has been surpassed by at least 3, maybe 4 rookies this year, although he is back on their Practice Squad again.
Then, in a few more weeks, we'll finally get to see how serious Linsley's injury is/was. He will be eligible to start practicing after 6 games.
