GREEN BAY, Wis. (AP) The Green Bay Packers have placed Sam Barrington on season-ending injured reserve after the starting inside linebacker left the opener against Chicago with a foot injury.

Defensive end Datone Jones was activated on Tuesday to replace Barrington on the roster. Jones served a one-game suspension for a violation of the league's substance abuse policy.

Barrington was seen in the locker room with a boot on his right foot. His loss is a blow to a defense that struggled last week against the run. Barrington sat out the second half of the 31-23 win over the Bears, when Matt Forte ran for 141 yards and a score on 24 carries.

Converted outside linebacker Nate Palmer replaced Barrington. Green Bay faces another tough running back this weekend in Seattle's Marshawn Lynch.
