The Packers might just use fullback Aaron Ripkowski on passing downs if Montgomery can't make it back for Sunday's game against Baltimore. He was carted back to the locker room and eventually ruled out with a knee injury.
Packers RB Aaron Jones expected to be sidelined 3-6 weeks with MCL injury, per source.
Jones had three carries for 12 yards and one catch for zero yards in the Packers' 23-16 victory at Solider Field in Chicago. Jones rushed for 125 yards against the Dallas Cowboys on October 8, and outdid himself two weeks later in a loss to the New Orleans Saints by gaining 131 yards on the ground via 17 carries. After all, they went into the 2017 thinking that Montgomery would be the lead back.
The 22-year-old Georgia native missed most of the 2015 season with the Miners because of an ankle injury. Missing all six weeks would leave him available for Week 17 against the Detroit Lions. He remained the Packers' featured back even after Montgomery returned from injury, relegating the converted wide receiver to snaps on a situational basis. Green Bay does not have a running back on the practice squad now.
