Bears nose tackle Andrew Billings was placed on injured reserve Thursday after undergoing surgery to repair a torn pectoral muscle.

While there’s a chance Jones can make it back in four games, Billings is expected to miss the remainder of the season. Bears defensive coordinator Eric Washington met the media earlier today and said losing Billings was huge.

Defensive tackle Andrew Billings suffered a chest injury in a Week 9 loss to the Arizona Cardinals, and the Bears will be without him for the foreseeable future. Eberflus said Billings will have surgery on his pectoral, which means Billings is likely done for the season. It's a huge blow to Chicago's defensive line.
