If the Lions had a list of objectives for Sunday's game against the Bears they could've put a check by all of them with a permanent marker after their 40-32 win at Ford Field.

Win the turnover battle -- check.

Find ways for running back Reggie Bush to use his speed in space -- nailed it.

Contain Bears wide receiver Brandon Marshall and keep Bears quarterback Jay Cutler flustered -- yes.

Win and take early control of the NFC North -- done.

Bush had 173 yards from scrimmage including a 37-yard touchdown run and the Lions (3-1) forced four turnovers en route to an easy victory over the Bears (3-1). They also scored 24 points in the second quarter and never relinquished control.

The victory moves the Lions into a tie with Chicago atop the division and because they beat the Bears the Lions hold an early tiebreaker if that becomes a factor later this season.

Quarterback Matthew Stafford finished 23 of 35 for 242 yards with a passing touchdown a rushing touchdown an interception and a lost fumble. Wide receiver Calvin Johnson playing on his 28th birthday had four catches for 44 yards including a 2-yard touchdown.

Cutler meanwhile finished 27 of 47 for 317 yards two touchdowns three interceptions and a fumble which Nick Fairley returned for a 4-yard touchdown to put the Lions up 37-16 near the end of the third quarter. Marshall had seven receptions for 79 yards.

Lions safety Louis Delmas had two interceptions and defensive tackle Ndamukong Suh had two sacks two tackles for loss and a forced fumble.

The game appeared to be an even matchup early and after the first quarter it was tied at 3-3. A 53-yard touchdown run by Matt Forte put the Bears up 10-6 early in the second quarter. But shortly after David Akers' third field goal made it 10-9 with 10:19 left in the second quarter everything changed.
