ATLANTA — Chicago made another huge mistake in the red zone, and the Atlanta Falcons held on for another wild victory over the Bears.

Michael Turner scored the go-ahead touchdown on an otherwise forgettable night, powering over from 5 yards with 3:06 remaining, and the defense held at the end to preserve a 21-14 victory Sunday night.

Matt Ryan threw two touchdown passes for the Falcons (4-1), who matched the best five-game start in franchise history. The Bears (3-2) will surely be moaning about all the mistakes down close that helped end their three-game winning streak: a fumble at the 1, an interception at the 9 and a crucial penalty when they had fourth-and-1 at the Atlanta 5 with less than a minute to go.
