The Green Bay Packers placed running back Eddie Lacy on injured reserve and signed rookie Don Jackson from the practice squad Thursday after it was revealed that the Packers’ top runner will need surgery to repair his injured ankle.
Lacy joins cornerback Sam Shields on IR and will remain there for at least eight weeks per league rules, while only one of the two will be eligible to return this season.
Lacy is set to hit free agency next year and has 360 rushing yards on the season, averaging 5.1 yards per carry on 71 attempts through five games.
His last full season came in 2014, when he rushed for 1,139 yards and nine touchdowns.
Jackson was cut by the Packers in June and signed to the practice squad in September. He has never taken a snap in the NFL.
The Packers also traded for former Kansas City Chiefs running back Knile Davis earlier this week to help shore up their ground game, while change-of-pace back James Starks is expected to return within the next few weeks after undergoing knee surgery.
