The Chicago Bears have been beaten for the first time this season in the NFL, losing 40-32 to the Detroit Lions.
There was nothing between the two sides in the first quarter, as Robbie Gould and David Akers each kicked a field goal.
Matt Forte added the game's first touchdown, sprinting 53 yards to put the Bears ahead early in the second quarter.
However, the Lions had a dominant spell before half time, as Matthew Stafford and Reggie Bush both ran into the end zone, while the quarterback also found Calvin Johnson for a touchdown.
Detroit extended their advantage late in the third when Nick Fairley returned a fumble four yards the team's fourth touchdown of the clash.
Alshon Jeffrey gave Chicago some late hope when he hauled in a 14-yard pass from Jay Cutler, while Earl Bennett found the end zone with 47 seconds left to leave the Bears eight points down.
Knowing that a touchdown and two-point conversion would take the game to overtime, the Bears attempted an onside kick, but the Lions were able to claim the ball to seal the victory.
