Maybe. The AP story notes that the Packers have kept a roster spot open, seemingly for WR Koren Robinson, by delaying CB Will Blackmon's placement on I.R. for his broken foot. It's possible that GM Ted Thompson might have something else in mind for that spot.
With TE Bubba Franks and RG Junius Coston nursing injuries the Packers might need the roster spot to fill their positions. Franks' injury leaves no other tight end on the roster except TE Donald Lee, so maybe they need to bring TE Ryan Krause off the practice squad as a backup. There is another tight end on the practice squad too, but Krause has more NFL experience so I'm assuming he would be the guy. On the offensive line, it's not just Coston's injury that's causing a problem but C Scott Wells might still be out another week or two with a broken eye socket and a couple other guys (LT Chad Clifton, OL Jason Spitz, and OL Tony Moll) have missed time and still may not be at 100%. Maybe the depth is still a concern after the bye week and OL Cameron Stephenson, who Pittsburgh cut at the end of training camp after selecting him in the 5th round back in April, will be added to the practice squad.
Still the most likely thing to happen is that they need to see Robinson in Green Bay later this week to see what kind of shape he is in before putting him back on the active roster. If he isn't in good shape, obviously he won't be in football shape and will have some rust because he hasn't played in a year, then I doubt Thompson would have any problems releasing him because his 2 year contract can't be much of a salary cap burden. He's only 27 years old so he should have some football left in him. From everything I read last season about his signing and suspension, Thompson believes that Robinson's troubles are behind him and they were all surprised that he got a one year suspension, although at the time it didn't seem to surprising to me with all the trouble he had gotten into over the previous two years with drinking and driving topped off with a high speed police pursuit.
If Robinson can return to the Pro Bowl form he showed in Minnesota as a kick returner, then he could be a real boost for the struggling special teams.
