GREEN BAY, Wis. (WBAY) – Green Bay Packers running back Eddie Lacy has been placed on injured reserve, according to a statement from the team.

ESPN and the NFL Network report that Lacy will need surgery on his injured ankle. It’s unclear if the surgery will end his season.

The Packers have signed rookie running back Don Jackson to the active roster from the practice squad.

Jackson will be the main running back against the Bears Thursday night, according to Ian Rapoport of NFL Network.

Jackson will take his first-ever snaps in the National Football League in front of a national audience. The 5’10”, 208-pound rookie was signed by the Packers as an undrafted free agent in May. He will wear No. 34.

Also, the team has shifted receiver Ty Montgomery to the role of running back, Rapoport says.

Lacy was previously ruled out for the Packers-Bears game Thursday night because of his ankle injury.

Running back James Starks is out with a knee injury.

Earlier this week, the Packers acquired running back Knile Davis from the Kansas City Chiefs.

Eddie Lacy is in his contract year.

The Packers-Bears showdown at Lambeau Field kicks off at 7:25 p.m.
