Does Roach's Play Indicate A Quicker Urlacher Return?

Apparently somehow I failed to notice that in yesterday's win against the Redskins, Nick Roach shifted over from the middle linebacker spot he began the game at to play the strong-side linebacker, while Blake Costanzo slotted in at the middle.

That may be fairly innocuous, but if Roach were going to be expected to play at the middle for any significant length of time, they'd want him to get as many snaps at the mike linebacker as he'd need, right? So surmised Moon Mullin:

If Urlacher were not coming back anytime soon - still not out of the realm of possibility, based on his healing powers - Roach would not likely be sent to a position he already knows well at the expense of one he needs all the time he can get.

So aside from the apparent revelation that Urlacher is really Wolverine on the football field, it looks like they're preparing for Urlacher to return in time for the season opener, which he's maintained all along. So Roach gets his playing time twice - both at his backup position primarily, then at his starting position later on.
