Johnson caught 11 passes for 146 yards with a pair of first-half touchdowns, and the Lions boosted their postseason hopes with a 34-17 victory over the Chicago Bears on Thursday. Johnson had been held under 60 yards in two of three games since returning from an ankle injury, and there were rumblings that the 29-year-old receiver was slowing down, but he quieted a lot of those concerns Thursday. After losing at Arizona and New England and falling out of first place in the NFC North, the Lions (8-4) spotted Chicago a 14-3 first-quarter lead before rallying with relative ease in the second. Detroit finished with a season-high 474 yards in its highest-scoring game since a 35-14 victory over the New York Giants in its opener. The Bears opened the scoring on Cutler’s 10-yard scoring pass to Alshon Jeffery, and they scored again after Jared Allen sacked Stafford, forced a fumble and recovered it at the Detroit 5. Bell put the Lions ahead with a 1-yard scoring run on fourth down — leaping toward the goal line and extending the ball just far enough for a touchdown.
