Packers to place RB Eddie Lacy on IR, Jackson to start at RB against Bears

Green Bay Packers RB Eddie Lacy needs foot surgery and the team will place him on injured reserve on Thursday, sources told ESPN's Adam Schefter.

The Packers on Tuesday acquired RB Knile Davis in a trade with the Kansas City Chiefs, but the team will start Don Jackson at the running back position when they face the Chicago Bears on Thursday night.

Davis, a 5-foot-11, 227-pound fourth-year player out of the University of Arkansas, was originally drafted by Kansas City in the third round (96th overall) of the 2013 NFL Draft. He played in 50 games for the Chiefs during the regular season, registering 775 rushing yards and 11 touchdowns on 233 attempts (3.3 avg.) while also hauling in 31 receptions for 260 yards (8.4 avg.) and one TD.

The Packers on Wednesday ruled out Lacy (ankle) for Thursday night's game. The team will determine later if his season is over.

Jackson has never played in an NFL game, including preseason action. Tonight will be his first snaps in his NFL career.
