DETROIT -

The Detroit Lions beat the Chicago Bears Sunday with a final score of 40 to 32.

Detroit now moves into a first-place tie with the NFC North-leading Chicago Bears (3-1) after Sunday's home game.

Reggie Bush ran for 139 yards and a touchdown and host Detroit rode a 27-point second quarter before holding on for a big division win.

Matthew Stafford threw for 242 yards and a touchdown and scored once on the ground for the Lions (3-1), who moved into a tie with Chicago (3-1) atop the NFC North. Detroit forced Jay Cutler into four of Chicago's five turnovers while sacking him three times and holding the Bears to 1-for-13 on third down.

Cutler completed 27-of-47 passes for 317 yards and two late scores but had three interceptions and lost a fumble. Matt Forte had a 53-yard touchdown run and 95 rushing yards for Chicago, which had two touchdowns and two two-point conversions in the final 4:00 but could not recover a pair of onside kick attempts.

Forte's touchdown put Chicago up 10-6 with 13:44 left in the first half, but the Lions scored 24 points in less than eight minutes before the break. Stafford got in on a quarterback sneak after picking up his own fumble at the goal line to make it 16-10 and Cutler threw a pick on the next play from scrimmage to set up Stafford's 2-yard scoring strike to Calvin Johnson, giving Detroit two touchdowns in 22 seconds.

Bush took it in from 37 yards out to give the Lions a 30-10 advantage late in the half and Cutler fumbled on a sack late in the third, with Nick Fairley taking in the recovery from 4 yards out to make it 37-16. Cutler found Alshon Jeffery from 14 yards out to get within 40-24 and then hit Earl Bennett with a 10-yard touchdown in the final minute before the Lions ran out the clock.

Detroit won at Washington last week for the first time in franchise history. Next week the Lions hope to ride the winning momentum as they take on Green Bay in Wisconsin October 6.

The Lions haven't won a road game against Green Bay since the early 1991.
