An already-occupied Packers injury report reached new heights on Saturday.

With Sam Shields, Jared Cook and Chris Banjo all out for Sunday's showdown in Green Bay against the visiting Cowboys, Quinten Rollins was also added to the questionable group. A group that consists of Eddie Lacy - who stands alone as the only healthy running back on the roster, Damarious Randall and James Starks. 

Starks, as ESPN's Rob Demovsky reported, may miss several weeks due to a meniscus injury in a knee. A few roster moves were made, including the release of Joe Callahan who was quickly snatched up by the Saints, and the short-tenured Brian Price, who will likely find his way back to the practice squad given whether or not he clears waivers.

The previously-suspended Mike Pennel and Demetri Goodson were both activated just two days shy of their expiring roster exemptions, which meant the Packers didn't have to make an immediate move to shift them back to the 53-man roster. Many were questioning whether or not the lone running back on the practice squad would be seeing a promotion in the near future. Given Saturday's likely concluded roster updates, that won't happen. For now, at least.

That lone running back is Don Jackson, who may have been facing a brief promotion to form cohesion with Lacy, who had been dealing with an ankle injury suffered last Sunday night against the Giants. I wrote this on Jackson in July:

"Jackson, originally a troubled teen from south Sacramento who took the hard road to the University of Nevada, was signed to the Packers as an undrafted free agent. His stout build pairs well with his quick, explosive maneuvering, almost similar to what (John) Crockett has shown with a larger body type."

As it stands now, he'll remain on the team's practice squad in favor of the two returning players. There's clear fondness from the Packers on Goodson and his ability to play as an appreciable gunner on special teams. Goodson doesn't bring fantastic depth to the cornerback position by any means, but albeit, depth is depth; he'll provide solidity to a unit that may be without Rollins on Sunday. Like his counterpart in Randall, he's also dealing with a groin injury while Shields remains in concussion protocol.

Come Sunday, Lacy and fullback Aaron Ripkowski may prove as the only two pure running backs seen in the offense. Randall Cobb and Ty Montgomery, who have combined for seven total carries out of the backfield this season, may also see time. Cobb was a scratch off this week's injury report despite a nasty hit suffered on the game-winning first down last week, so keeping him away from the tailback position may be desired. 

On the opposite side of the ball, the historically efficient front seven will be up against a stout Cowboys offensive line. A fact that may have been the driving force behind activating Pennel for Sunday rather than keeping him sidelined with his roster exemption as aforementioned.

The Packers and Cowboys kick off at 3:25 PM CT on Sunday and the home team will be sporting their 1937-1948 throwback uniforms. The club will also honor Brett Favre at halftime and present his name on Lambeau Field's  facade alongside other cemented greats to have played for the organization.
