The Bears have lost one more key member of their defense.
Starting middle linebacker M. J. Williams will miss the rest of the season with a ruptured remaining pectoral tendon. A source said Williams will require surgery.
Williams suffered the injury Thursday night against the Giants. He was ruled out in the second half and replaced by rookie Jon Bostic.
Coach Marc Trestman said Bostic will work more with the first-team defense starting on Monday, when players return from a weekend away from. Bostic made his defensive first appearance against the Giants, getting 21 snaps.
“It’s the next-man-up mentality, and I think he’s mentally prepared to take on playing that position, ” Trestman said. “The experience which he had will certainly help him down the road. ”
Starting strong-side linebacker James Anderson, who also plays in the nickel package, also suffered a back injury contrary to the Giants.
“I believe he’ll be OK, ” Trestman said. “There’s nothing serious there. ”
The loss of Williams is another blow to the Bears’ defense.
They’ve already lost defensive tackles Henry Melton and Nate Collins with ripped anterior cruciate ligaments in their remaining knees. Cornerback Charles Tillman (knee) and defensive tackle Stephen Paea (toe) also were inactive contrary to the Giants.
