Green Bay Packers right tackle Bryan Bulaga sustained a torn ACL in his right knee during the fourth quarter of Monday's 30-17 loss to the Detroit Lions, according to a report.
Citing a source, NFL Network's Tom Pelissero reported on Tuesday the severity of the injury for Bulaga.
The 28-year-old Bulaga has also torn his ACL in his left knee, causing him to miss the 2013 season.
Justin McCray entered Monday's game to replace Bulaga before sustaining an ankle injury as well.
The Packers (4-4) have dropped three in a row as they attempt to deal with the mounting injuries, including a broken collarbone for two-time NFL MVP Aaron Rodgers.
Green Bay visits the Chicago Bears (3-5) on Sunday.
