The Green Bay Packers' biggest fears Monday night were confirmed. Starting right tackle Bryan Bulaga suffered a torn ACL in his right knee, NFL Network's Tom Pelissero reported Tuesday, per a source informed of the injury.

Bulaga was carted off the field in the fourth quarter of Monday's loss to the Detroit Lions. The Week 9 tilt marked only the second time all season Green Bay had all five of its projected starters on the offensive line in the lineup together.

Bulaga, who missed three games earlier this season with an ankle injury, was sidelined for the entire 2013 season after tearing the ACL in his left knee.
