Michael Floyd caught a pair of touchdown passes from Drew Stanton, from 42 yards and 12 yards out, giving them an early lead they never relinquished. Detroit's Matt Prater hit a pair of field goals, first a 50-yard kick in the first quarter then a 28-yarder late in the second quarter, to cut the lead to 14-6 at halftime. Neither team scored in the second half. The Lions, plagued by several penalties on both sides of the ball, saw their four-game winning streak snapped.
