When the Bears got the ball back without allowing the Steelers to answer the second DJ Moore touchdown, Kyle Monangai punched it in for six points, which all but sealed the victory for the Bears. The defense made a couple of nice plays late in the game, but this touchdown was needed as it eventually served as the winning points.

Chicago Bears defensive end Montez Sweat had two sacks against the Pittsburgh Steelers, and nearly had a third. “It would have been my first hat trick,” he said.

Instead, PFF's grades tilted heavily in favor of the Bears' offensive line, with guard Jonah Jackson leading the way with a 76.5 grade. Jackson exited the game with an eye injury after 45 snaps, but his body of work before his exit was good enough to lead the way.

The Chicago Bears defeated the Pittsburgh Steelers, 31-28, on Sunday to win their eighth game in the last nine. They're now 8-3 and retain sole possession of first place in the NFC North.

Sweat had three tackles (all solo), two sacks, three tackles for loss, the aforementioned forced fumble (and recovery), and two QB hits. The Bears needed a big game from the D-Line given the injuries to the other levels of the defense, and Sweat came through in a big way.
