81 Geronimo Allison WR

Allison (groin) won't be eligible to be activated from injured reserve this season after the Packers designated wideout Jake Kumerow (shoulder) to return from IR on Wednesday, Tom Silverstein of the Milwaukee Journal Sentinel reports.

After bringing back fellow receiver Trevor Davis from IR last week, the Packers used their second and final designation on Kumerow, a preseason standout who seems to be near full health. While Allison projects to be close to 100 percent before the end of 2018, he was never an ideal candidate to return from IR since he wouldn't have been eligible to play until the postseason. Allison shouldn't face any restrictions when the Packers reconvene for OTAs next spring.

The Packers placed Allison (groin) on injured reserve Tuesday.

The IR move means that Allison won't be available for at least eight weeks after he underwent surgery to address a core-muscle injury, ending any possibility of him playing before the regular season concludes. Allison could be a candidate to come off IR during the postseason should the Packers qualify, but the team would first have to designate him as one of two players eligible to return. His absence for the entire back half of the Packers' schedule paves the way for rookie Marquez Valdes-Scantling to handle a regular role in three-receiver sets alongside Davante Adams and Randall Cobb.

Allison is expected to undergo surgery on a core muscle injury, which will include a recovery timetable of six weeks, Ian Rapoport of NFL Network reports.

After an examination by Dr. William Meyers, it was determined Allison will require a procedure to treat the lingering injury, per Rob Demovsky. The development comes on the heels of coach Mike McCarthy stating Monday that Allison has a significant injury. Allison is a candidate to be placed on injured reserve following surgery, but such a roster move would ensure he won't play again until Week 17, at the earliest. In his stead, the Packers will continue to roll with Marquez Valdes-Scantling as the No. 3 wide receiver.

Head coach Mike McCarthy indicated Monday that Allison (groin) is dealing with a significant injury and could be out for an extended period of time, Michael Cohen of The Athletic reports.

Rob Demovsky of ESPN relays that Allison may require surgery, but it isn't clear if the receiver is expected to miss the remainder of the season. In any case, rookie Marquez Valdes-Scantling figures to become an even more prominent figure in the Packers offense in the immediate future.

Allison (groin/hamstring) was downgraded from doubtful to out for Sunday's game against the Patriots.

Allison has been marred by a concussion and hamstring issue over the last month and then the groin injury cropped up this week. Rookie Marquez Valdes-Scantling has shown a solid rapport with quarterback Aaron Rodgers in recent weeks and should take on a larger role against the Patriots with Allison again sidelined.
