The Bears received a scare in the Seahawks game when wide receiver Johnny Knox bent his back awkwardly after taking a hit on Seahawk's defensive end Anthony Hargrove while trying to recover his own fumble. Knox remained down for nearly ten minutes leaving Bears fans in shock. The major hit ended the receiver's season, and he was placed on injured reserve. In the game, the Bears would lead 14-7 in the first half, but would end in disaster when they were outscored 31-0 in the second half including two defensive touchdowns. First, Hanie threw a pass that was intercepted by the Seahawks Red Bryant and he returned it 20 yards for a touchdown. The second one which Hanie threw was picked off by Brandon Browner and he returned it 42 yards for a touchdown. Hanie would then be benched late in the game and replaced by Josh McCown. The loss gave the Bears a .500 winning percentage and a 7-7 record.
